@regg Well I have everything you mentioned. I bought the CODA 07x because it is a bit warmer than the HPA4 and also has dual XLR outputs. It is amazing with my RAAL SR1a headphones which need warmth, though less today with a fabulous new SR1a specific Convolution filter. I missed the HPA4 on my office floor standers so I have both preamps setup again today in my office with all my sources. I have 15 foot XLR’s on the 2 preamps that I easily change at the amp end whenever I want to use a particular preamp. So with all that upfront I can tell you that I know exactly how they compare to each other. They are both great preamps. The CODA is warmer and nosier than the HPA4. That bugs me a little bit but it sounds great with music and the hiss is not noticeable when music is playing. The HPA4 is extremely quite so you notice other gear that is not as quiet. You already know how detailed and amazing the Benchmark stack sounds. The CODA 07x makes things a little less detailed and maybe lively. For example, when I listen to Led Zeppelin I prefer the HPA4.
As I write this I am listening to some Bobby Womack on the CODA 07x and it is great. I would not get the CODA 07x in your situation. I would get the Gustard X26 Pro DAC for $1500 from these guys. Gustard X26 Pro Balanced DAC Preview (shenzhenaudio.com) It has that extra warmth that the DAC3B does not have. Though on some music I prefer the DAC3B. The Gustard is an incredible DAC and do not let the price fool you. I just sold the AudioMirror Tubadour III SE DAC and want a replacement for it on my office. Something a little warmer than the DAC3B (for my RAAL SR1a specifically). I prefer the Gustard X26 Pro to the AMT3SE. My Gustard X26 Pro was moved to my downstairs mini system since I brought the HPA4 to my office again. So I was thinking of getting a second Gustard X26 Pro for the office. That is how much of a fan I am. The other DAC that I am considering is the AudioByte Vox | ZAP at 3x more cost. The 2 reasons for this choice is that the AudioByte was compared with the Gustard X26 Pro by a reviewer I like and he gave compelling reasons to have both DACs. The AudioByte will also fit better in my crowded rack compared to the Gustard. My tastes in audio also align well with this reviewer. Soundnews - Everything about sound |
@regg BTW - welcome to A’gon.
I sold my AMT3SE DAC on Sunday, Meze Empy headphones (today), and a KRELL integrated last week so I have an itch to buy a DAC.
I think a better combo than the AHB2 and the CODA 07x would be the CODA #8 and the HPA4. I am going to get the CODA #8 later in the year. I am currently happy with a $1500 D-Sonic M3a 800s Class D amp. It is not as good as the AHB2 but it works better on my speakers. I use the AHB2 on the office SR1a and also my downstairs mini system.
If you want another review of the Gustard X26 Pro send me a DM in A’gon. Someone I know bought the Gustard and wrote me his thoughts on it. Exactly how I felt but he is more eloquent in his descriptions.
BTW - if you get the Gustard X26 Pro (a silver one) and want to save some money via a trade. I have a 2 week old silver Gustard X26 Pro and want to get a black one instead. The seller in China replaced my 2 month old unit because I had an issue with using it as a preamp. It cost me $116 to send by USPS to China and they sent me a new one. Great seller. |
No, my BM stack is number 1. I have taken the BM gear out
(moved it downstairs)
several times the past 6 months and always missed it. I replaced it with the following.
- CODA CSiB integrated
- KRELL K-300i integrated
- Gustard X26 Pro as a preamp
- D-Sonic amp
Maybe more stuff that I cannot remember. I liked the above stuff a lot and I thought they were great. However, I always missed the BM stack when I did not have it in the office.
The AHB2 is not ideally suited for my Thiel CS3.7 (even in mono). It sounds very nice but a more powerful amp gives a more impactful sound on these specific speakers. So I do not use the AHB2 on the floor standers but I will never sell the AHB2.
In a few years, when my young son no longer uses the living room for his gear I will put the BM stack in there with a speaker ideally suited for the AHB2.
I agree with you that the BM stack is not great on everything. I blame that on the source music in those cases. However, in that situation I think my hybrid BM + CODA approach works nicely. If I did not have the RAAL SR1a I think the Gustard X26 Pro alone would solve that 20-30% perfectly. |
|
@regg I forgot to mention that the store that has the Gustard also has a 30 or 45 day home trial.
I personally want to try the Benchmark stack on the Yamaha NS5000. I think it would be great.
When I demoed Harbeth I thought it may be very good with the BM stack. |
These streamer suggestions are great. I had a great improvement in my sound when I went with a Ubiquiti network switch ($200) and fibre optic cable directly from that to my Sonore OpticalRendu. Then from there USB to my DAC.
When I first heard this setup I was amazed at how much an improvement over my 5 year old Sonore microRendu. I actually bought a second "OpticalRendu for ROON Only" ($999) for my AudioMirror DAC. My streaming quest is now done.
I have a noisy network with my music server on a cheap computer far away in another room. That room is setup on my home network by a PowerLine subnet. So nothing anyone would say is noiseless. However, when the bits get to that last mile before the DAC I believe the fibre kills the noise. Otherwise, my setup should sound awful.
I am going to buy the AudiByte VOX | ZAP DAC next week. It has built-in streaming that is supposed to be advanced (on the not yet available HUB module). It will be interesting to compare the OpticalRendu with the built-in network streaming on the AudiByte.
If the source is bad then on the BM stack the sound is bad. |
@regg the Aurrender does not support ROON (if that is important to you).
I had the pretty cool ROON READY Matrix Audio Mini-I 3 Pro DAC in the house for about 6 months ($899). I sent it off to my buddy who does not want to struggle with streaming. It has a lot of streaming choices.
I tried 3 of them and compared.
- built-in network streaming using Ethernet
- my old Sonore microRendu via USB
- built-in WiFi on the DAC
The first 2 wired setups sounded a bit better and was infinitely more reliable. On Wifi I would have music playing for a few hours then all of a sudden the music got all scrambled and I had to restart the DAC. There are some posts on streaming threads that give some arguments as to why WiFi is bad for streaming. The only company that I know that advocates for WiFi is the well regarded Auralic.

@mapman The new KEF sub has a feature for apartment use. |
I got permission to post this mini review of the Gustard X26 Pro. The A22 referenced is the Gustard A22. The A22 seems to sound like the DAC3B. Now for the X26 PRO:
The X26 PRO is potentially the warmest sounding DAC I have ever had in my system. It literally makes digital sound closer to the warm sound of vinyl than any DAC I have had. However, this warm sound does not eliminate detail. This DAC passes more detail than any DAC I have ever had, period. It is an entirely different experience listening to this DAC compared to the A22. The X26 PRO has a seductively warm sound while presenting low level detail that is difficult to comprehend.
I am generally not one to get off on details in a recording that were not intended (like cars going by in the background that were caught by mics in the recording). But I was listening to Tin Pan Alley (SRV) on Couldn't Stand the Weather, and approximately 7 min and 30 sec into that song there is what sounds like a car horn go off in the far, far right deep in the background. I have probably listened to that track 50+ times, and I never, ever noticed that. Seriously, check it out. I first heard it on my hi-rez vinyl transcription. I literally had to replay that part several times as I thought originally it was a car horn coming from outside my house. I then went on to check the CD version of this album (as perhaps this was an artifact of the vinyl version). And sure enough it is in the CD version as well. Not quite as prominite, but I could still hear it without straining.
The X26 PRO has a better soundstage. I think one of the hardest things for components to do is create an image in the deep rear corners (outside of the speakers). The X26 does this better than the A22. My speakers disappear in the soundstage better with the X26 than the A22. The X26 also offers a wider soundstage.
The X26 has better overall micro and macro dynamics. At low volume levels the X26's sound is so good and seductive.
Anyway, I could go on, and on. But the bottom line is that the X26 PRO is in a different class of DACs from the A22. The A22 is a great DAC for $1250. But at $1500, the X26 PRO is an entirely different animal. If you want a more neutral sound, the A22 is more neutral. But if you want a more vinyl kind of warmth with digital, the X26 PRO is an amazing value and performer at $1500. I will add to this with my review. A great DAC |
Guys like @atmasphere say that if the gear supports the AES48 balanced standard (like Benchmark) different XLR cables should not effect the sound much. I feel that way with the Benchmark gear. I use the BM XLR between the preamp and amp (15 feet). The source to preamp are all Audience AU24SE expensive XLR cables. I had these Audience cables from long ago and compared them with the BM XLR’s. I thought the AU24SE were a little better, though that could be phycological because I spent a ton more money on them.
Speaker wire from the AHB2 to the speakers had a big effect on the sound. I tried 3 different cables and my preferences from most to least.
1) Audience FrontRow (with SpeakON termination)
2) Audience Conductor SE
3) Benchmark speaker cable with SpeakON
BTW - I did test the DAC3B with the headphone amp so that I could eliminate the 15 foot preamp to amp cable from the test
BTW2 - I have a warm sounding SONY SCD-1 SACD player from 20 years ago hooked up to the HPA4. It has never sounded better than today. I did not like it as much on the CODA 07x. Maybe too much warmth. |
A mea culpa for me on the CODA 07x preamp making a hiss on my floorstanders (not RAAL SR1a headphones). This was really bugging me and some other folks on WBF were telling me they do not have a hiss. So tonight I removed my D-Sonic amp and put in a single AHB2 with the CODA 07x. The hiss was gone for the most part as was with the HPA4. The HPA4 seemed a tiny bit quieter.
It looks like I should get the CODA #8 amp for my floor standers sooner than later. |
@regg You should try the Gustard X26 Pro on the home trial. Having that Gustard even as a backup DAC is a big win.
The reviewer I referenced actually compares the AudioByte to the Gustard. He loved both with the AudioByte slightly preferred. The AudioByte does have great potential to become great with the firmware updates and also the HUB. With the Gustard you are set with the existing sound unless you get the external clock which may make things better or worse.
I must say that this tread has got me a bit annoyed with that hiss I reported with the Class D amp and the CODA07x. It was much lower wit the HPA4. It did not bother me until I paid attention when I made that post. I was going to buy the AudioByte tomorrow and then the CODA #8 later in the year (close to 2022) but I may flip that around.
The Benchmark DAC3B is pretty good in the current setup. It is also great with the CODA 07x.
I am surprised that you also have FrontRow with SpeakON. I thought I was the only person that did that. On my RAAL SR1a the FrontRow cables was more noticeable than on my floorstanders. Seems crazy to have $4K speaker cables on a $3.5K headphones but spending 4K on cables is also kind of crazy. |
@regg I hope you can post your opinion on the Gustard on this thread.
I am going to get that CODA #8. I cleared up my IRS tax payments yesterday was going to use the money for food, but I think I will get the CODA #8 instead.
BTW - I am going to move my silver D-Sonic amp to the downstairs to play with the silver Gustard I have. So I am not going to switch to a Black Gustard. The CODA will replace the D-Sonic on the office system. |
@regg Well this thread got me spending some money on gear a bit faster than anticipated.
After my rearranging of my gear last night, I am now listening to the floor standers with my CODA 07x connected to a single AHB2 and DAC3B streamed by fibre optical. This sound is killer. The single AHB2 is not powerful enough for my speakers but damn it sounds great. A little warmer than the HPA4, both are great.
I decided to get the CODA #8 today and made the purchase. I am still waiting on word whether I get SpeakON terminations on the #8. I want a switch on the amp to toggle between the duplicate speaker connectors. That way I can use my RAAL SR1a with the adapter box. My floor standers can also work from the CODA #8 without additional electronic circuitry to the floor standers (RAAL adapter box).
I am not sure about getting the AudioByte now. I may just get another Gustard X26 Pro next month. Due to costs.
My D-Sonic amp and the silver Gustard are working great together with KEF LS50s downstairs entertaining the family as I write this. I returned my first Gustard because it had an intermittent issue when used as a preamp. I have not had this reappear with the replacement DAC. |
@regg I replaced the CODA 07x and put in the HPA4 with the same XLR. The gain was a little off so I increased the volume. I am listening to the same album on hi-res that I played earlier on the CODA 07x, Led Zeppelin II.
On the all BM stack there is a bit more detail, such as on the first song. There is also a tiny bit of hardness to the sound that was not there on the CODA 07x.The soundstage also seems a little smaller than with the CODA.
This next observation confuses me. With the all BM stack I feel the single AHB2 is not enough juice for the Thiel CS3.7 (it is pretty good). However, with the CODA 07x I feel the single AHB2 is still lacking a bit of power but the sound itself seems more powerful. Now this is a hard rocking album so the more powerful sounding CODA seems to sound better with the AHB2.
I would not say this is the case all the time. In the past, I had the AHB2 in mono with theHPA4 and the sound was more powerful. I never tested the CODA 07x with AHB2 in mono. I doubt that will happen now that the second AHB2 is my headphone amp for the RAAL SR1a.
Turns out I cannot get a switch on the CODA #8 to select the speaker connectors. So it is the regular #8 I will be getting.
I don’t think I got anything more to add on this. |
@mrpsync Since I have 2 preamps I was able to connect the Benchmark DAC3B by RCA and XLR at the same time to each preamp. I spoke to Rory Rail at Benchmark about doing this and he said it is fine and a lot of people use it this way. I also setup the Gustard the same way. The AudioMirror TUbadour III SE that I just sold could not have both RCA and XLR connected at the same time. Vlad told me this and I confirmed it by testing it. I never got confirmation if the Gustard supported this type of dual hookup. The sound I got from the RCA seemed very similar to the XLR. I never hooked up both the RCA and XLR of the Gustard to the same preamp at the same time. So there is some variation in the signal path from the different preamps. However, one reason that I am looking at another Gustard is that the RCA and XLR both sound good. On the DAC3B the XLR sounds better but it is also much louder than the RCA so that could be it. Balanced vs. Unbalanced Analog Interfaces - Benchmark Media Systems Also could you confirm the "replacement" Gustard corrected any issues you had with it serving as both Dac and Preamp direct to amp? Yes, everything is working perfectly now. Also note, that the person that owns the Gustard whose review I posted never had the issue I had with the first Gustard. BTW - I would say that the Gustard is a better DAC than the DAC3B. If I could have only 1 of those 2 it would be an easy choice for the Gustard. It is a really great DAC. However, the DAC3B has perfect synergy driving the AHB2 directly. The Gustard sounded good driving the AHB2 but I would guess the DAC3B is the better fit DAC direct to AHB2. |
@regg If the AHB2 had more power then I would not have bought the CODA #8. More power on the CS3.7 make them sing. I tried the following:
- CODA CSiB integrated
- KRELL K-300i
integrated
- D Sonic M3a 800s amp
- AHB2 in mono
The CODA 07x and AHB2 is really good maybe the best sound of them all (but on the CS3.7 the AHB2 lack grunt).
I would also say this is end game stuff for me. I spent about 2 years researching and then buying. I am pretty much done after I buy another DAC.
I have the opportunity to buy some speakers for the downstairs but that really should wait about 5 more years until my son is older. |
I will add this post here since I think it is relevant on all things Benchmark. 1) I brought up the Gustard X26 Pro to my office because the RAAL SR1a sounds best with it and the floorstander are great too (as with the DAC3B and floorstanders) 2) Now I need a DAC for the downstairs to play in my digital only mini system. Mostly background music so no need for the best. 3) Looked around for DACs with volume control and was not too excited about buying another DAC at a low price range other than the Gustard. However not excited about having 2 of the same DAC. My Benchmark DAC3B does not have a volume control and it is a bit redundant with the Gustard next to it. Ideally I would just buy a second HPA4/LA4 preamp and take the DAC3B downstairs, but that is expensive and a bit of a waste with only 1 input required. So I came across my favorite reviewer comparing the Topping pre90 to the HPA4. Topping Pre90 + Ext90 Review - Pre-amp my Power-amp! (soundnews.net) HPA4 can accept higher voltages compared to Pre90, since it can be used in studios and in the Pro Audio world, where audio interfaces are working with much stronger signals like 15V. Without too much fanfare, I will just mention that I find them equally clean and transparent, I’m experiencing the same amazing control of the drivers, the same airy performance, the same incredibly low channel crosstalk that improves the scale on all axis with my speakers. They are almost indistinguishable and in a blind test, I couldn’t differentiate them or guess which is which. At only 1⁄5 of the price, Pre90 is pretty much on the same level with HPA4. Benchmark unit still has the best graphical user interface I’ve ever experienced, with Pre90 you are not getting a colorful touch-screen and several analog outputs, but you are getting the same clean and undistorted performance. Ext90 adds several analog inputs, so the gap between them is shrinking considerably. Would I sell the HPA4 and get a Pre90 + Ext90 instead? I probably wouldn’t do that, because HPA4 has more analog outputs and it’s still my main headphone amplifier. But if you are a hardcore loudspeaker listener and if I you have one or two sources and pair of loudspeakers, then I would definitely sell the HPA4 and get the Pre90 instead.
Both units have same detail retrieval, the same transparency, same sharpness, frequency response, the same speed and impact. Soundstage is identical and depth is exactly as deep. There was just a minor difference in terms of midrange rendition, while HPA4 was always dead-neutral in its presentation, Pre90 was adding a pinch of midrange density, not by a whole lot, but enough to be detected with acoustic music.
If you ever dreamed about owning an HPA4 or LA4 by Benchmark but never had the funds, now is your chance to have the same kind of performance at a much lower price point. I remained speechless and frankly, quite impressed by the performance of the Pre90. Today, I bought the Topping pre90 on the 30 day home evaluation. I previously had a Topping A90 headphone amp and the sound was pretty good, almost as good as the HPA4 headphone. So hopefully a homerun and perfect match with the DAC3B. |
@mapman This reviewer is on the money for me. I bought the following based on his reviews and I got exactly what I expected.
- Benchmark HPA4 (was going to get the LA4)
- Gustard X26 Pro
- Matrix Mini-3 Pro (my buddy has this now)
- Topping A90 headphone amp
(my buddy has this now)
I expect the Topping pre90 to also work for me.
@regg I labeled my cables and since they are XLR's it is really easy to hook up. The Gustard X26 Pro, CODA 07x, HPA4, AHB2, DAC3B are great paired up in any combo. I will be adding the CODA#8 to this soup. I have no desire to buy anything in the uber expensive range.
Note that the CODA 07x does not have a power swatch, it is always on. So I make sure I change the active preamp input to a source that is turned off when I am removing the XLR from the AHB2. |
@gagliano01 I recently had a long conversation with Ric Shultz about his modded Putifi amps. I wish I had known about the EVS Ultimate attenuator. I always wanted to try one. It is the same price as the Topping per90 that I just bought. Though I expect that preamp to be perfect for my needs.
I have the opposite observations with the HPA4 in-between the DAC3B and AHB2. I thought everything was better. Volume control at low levels was much better with the HPA4. |
This next observation confuses me. With the all BM stack I feel the single AHB2 is not enough juice for the Thiel CS3.7 (it is pretty good). However, with the CODA 07x I feel the single AHB2 is still lacking a bit of power but the sound itself seems more powerful. Now this is a hard rocking album so the more powerful sounding CODA seems to sound better with the AHB2. I wrote this about the HPA4 not sounding as powerful as the CODA 07x and not making sense. I figured out how this happened the next day. I forgot to post that here. When I brought up the HPA4 from downstairs I wired up the MONO output to the RIGHT speaker. I was doing this without looking and forgot that the RIGHT channel is the middle connection on the HPA4. So that explains the quote above. I later disconnected everything, cleaned the gear and set it up with a nice layout and less jumbled wiring. The next observation is also not fully correct. The part about the soundstage being smaller was an artifact of the MONO connection. The greater detail and harder on top than the CODA still applies. I compared this again. On the all BM stack there is a bit more detail, such as on the first song. There is also a tiny bit of hardness to the sound that was not there on the CODA 07x.The soundstage also seems a little smaller than with the CODA. The preamp output connection (for both preamps) I use now will not get changed in the future. Only the XLR connection at the amp end. |
@wturkey The CODA 07x is amazing and make my RAAL SR1a sound like million dollar speakers (no room to deal with). I have a ton of experience with the RAAL and the CODA 07x is magic on them. However, whenever, I hear something really great on the CODA conected to my floor standers I tell myself to remember to listen to that on the HPA4. I find the HPA4 my favorite piece of gear. I would not say the HPA4 is better than the 07x but on my floor standers I tend to prefer the HPA4 sound (or lack thereof). Just a matter of preference.
If my speakers were not such a current pig I would not be getting the CODA #8.
I can also tell everyone that CODA and Benchmark sound incredible together.

@regg In 2 weeks I am going to setup a ROON system for someone. He has used DEQX gear for 15 years (maybe 5 models). I am going to show him the ROON setup with DSP run via CONVOLUTION filters for my RAAL SR1a. This is what I run for both my floorstanders and my RAAL (my office is small with big speakers). These are 2 different DSP implementations done by Accurate Sound out of Canada.
I told him that the Convolution filter will likely be much better than his DEQX gear. I think the Convolution filters will be better because it uses a computer and you are not limited by processing power on a computer verses a dedicated piece of audio gear. Need more power? Just buy a more powerful computer and use the same or more demanding Convolution filter.
Regarding the crossover for the AHB2 + sub. Did you read the link I posted earlier describing how to setup a sub with the AHB2?
I just played on of my favorites disks, Earth Wind and Fire - Greatest Hits on the CODA 07x + Gustard X26 Pro and AHB2 + Thiel CS3.7. I was so mesmerized by the music I stopped my work and just listened to the whole album. I then played the album again. This time I put in the HPA4 and used the same XLR from the Gustard to make an apples to apples comparison. The HPA4 is a little clearer more detailed and beautiful but that CODA 07x and Gustard combo was a bit warmer and was magic.
BTW - I use fibre for my streaming so the computer noise is not a factor. I am however limited to only having DSP done for my DAC, not SACD or tuner which are analog outputs.
@unsound There is a market for an AHB3 but BM seems to think the amp is perfect as is and if you need more power then run it in mono. Though in mono it is not rate at continuous power in 2 Ohm. The stereo version is rated at 2 Ohm continuous power (something in the 250 watt range).

Someone wanted my take on the Topping pre90 vs the HPA4. I only got the Topping pre90 today and it has only about 6 hours on it.
I must say I am impressed by this little preamp. It sounds a lot like the HPA4. That is they are both ultra quiet and I am not sure what I loose sonics wise with the pre90 over the HPA4. I do lose an RCA input and the great volume control of the HPA4. Though the Toppings volume was much better than the Topping A90 headphone amp I had at one time (and gave away).
I love the fact that the output on the pre90 has a switch to select RCA or XLR. In my situation, with my CODA 07x preamp being part of the equation and that unit not having a power switch (always on), it was too dangerous for me to setup the RCA and XLR outputs on the HPA4 (just used XLR). I do not think the HPA4 has such an output switch and if it did it is too complicated to keep track. The pre90 makes this easy with the GUI and buttons.
I did some listening to my Sony SCD-1 SACD/CD (modified) player into the Topping pre90 by XLR and then RCA into my D-Sonic M3a 800s and then into my RAAL SR1a. I am thinking this pretty amazing and something I was too afraid to do with the HPA4. The D-Sonic also has a switch to select RCA or XLR input.
The Sony SCD-1 does not have DSP done like my digital streaming. It sounds great since the room is not part of the listening experience with the RAAL SR1a headphones. I however, do use a Convolution file on my RAAL SR1a + DAC streaming and it is better, but this vintage 20 year Sony SACD/CD is one of the best ever built and still sounds killer. I will be listening a ton more to the Sony if I keep the Topping pre90.
I still need this unit to burn in more and test it with my streamers into my Thiel CS3.7 floor standers. I have 15 foot XLR cable from the preamp to the Benchmark AHB2 mono amps. It sounds very good so far but I will do some more detailed comparisons after more hours on the Topping.
Here are some reasons for me to keep the Topping pre90:
- I sold my Meze Empy headphones last week because with the way my RAAL SR1a are now setup with the Convolution from my streamers and also the analog sound today with the Sony SCD-1 the Empy was toast. I bought the HPA4 over the LA4 because of the Empy needing a headphone connection.
- the benefit of the RCA/XLR output switch on the Topping pre90.
- most importantly the pre90 sounding so much like the HPA4 so far. I am starting to love my CODA 07x as my main preamp and the HPA4 or Topping as second fiddle.
I am now playing the Benchmark DAC3B with a Convolution filter designed for the RAAL SR1a into the Topping pre90 by RCA. The output is Topping pre90 RCA to the D-Sonic amp. It sounds great, though not as great as the CODA 07x in this scenario. This time I have to give the main credit to the Convolution filter for making the Topping and DAC3B sound excellent on the RAAL SR1a.
BTW - it is almost 3AM and I am still listening to the pre90 without any complaints about the sonics. A great sign. I am tending to think I will be selling the $3000 HPA4 and go with the $600 Topping pre90.
|
If anyone is interested. I compared the Benchmark HPA4 vs the Topping pre90. I could not tell a difference. They sounded the same. I sold the HPA4 for almost the same price I bought it for and now use the Topping pre90 ($599).
In fact my CODA 07x has not had any play with my floor standers for almost 2 weeks since I have be using the Topping. I am really armored with the Topping. I do use the CODA 07x for my RAAL SR1a.
The Topping pre90 is like the HPA4. It gets out of the way and let’s the other components dictate the sound. I loved this unit so much that I also bought the Topping ext90 ($250) which adds 3 more XLR’s and 1 more RCA. I cannot believe this level of quality for the price.
My CODA #8 amp should be shipped soon. I am certain it will sound great with both the Topping pre90 and CODA 07x. I currently use the Benchmark AHB2 monos. They sound incredible with both preamps. If I was smarter I would not have bought the CODA #8.
BTW - the Topping pre90 does not have the amazing headphone amp as the HPA4. However, now that I only listen to the RAAL SR1a headphones the HPA4 headphone amp was never used.
|
@mrpsync I was using the Topping pre90 for 2 to 3 weeks straight on my floor standers which were driven by the AHB2 monos. It sounded awesome. I do not miss the HPA4 since the Topping pre90 sounds like it. I may have mentioned it on this thread that the HPA4 has way more useful features than the Topping pre90. The pre90 is really bare bones but that is all I need. Today I have the CODA 07x back in the mix and it is also amazing. Every time I switch preamps I tend to like the new one more. Which is a good reason to keep both. My CODA #8 is finally built and is being burnt in at CODA this weekend. It will ship on Monday. I had SpeakON speaker connections added to the #8 to play with my Audience FrontRow cable which is used by the AHB2 SpeakON terminal. The SpeakON’s added some delay to my amp delivery. I use my DAC3B regularly because I find it a bit more detailed than the Gustard. I definitely tested this out a few days ago with my RAAL SR1a. I love both DACs and have come to appreciate the DAC3B even more now. I always prefer a preamp for my DACs. I have not spent mega bucks on DACs so I do not know if other DACs have better preamp capabilities, but the DACs I have listened to have benefited with a preamp. One of the top 10 DACs these guys ever measured. Gustard X26Pro Review (Balanced High-end DAC) | Audio Science Review (ASR) Forum |
@mrpsync The Topping pre90 sounds good with the DAC3B and the Gustard X26 Pro. If you can swing it keep both. They sound different. In my case, with the RAAL SR1a headphones the Gustard X26 Pro was a must. However, that gap has closed recently with a Convolution filter for the SR1a. I totally agree with the comments you 2 guys above have made about the DAC3 and the Gustard X26 Pro. I hear it the same way. I sold the DAC3B 2x before and regretted it both times (I moved, had kid, etc...). I am never selling the DAC3B. Not sure how long the Gustard X26 Pro will last (it runs warm), but I will enjoy until then. I am not sure about what you are referring to with the $1200. If it is the Gustard buy it from the Chinese retailer

If anything goes wrong they will replace it. |
The CODA 07x is pretty amazing. It is at the level of the Luxman c900u preamp at $15K. I think I would take the CODA over the c900u. I am comparing these 2 because they are sort of similar sonically. A little warm for the CODA a bit warmer still for the Luxman.
As I write this I am playing some music via my Sony SCD-1 SACD player into my Topping pre90 and then to a D-Sonic Class D amp which then goes to my RAAL SR1a headphones. This is the first time in a long time I have heard the RAAL SR1a naked (no DSP). It sounds great with the 20 year old disk player. The Topping really gets out of the way and lets me hear the SACD player. The Sony SCD-1 does not sound as nice with the CODA 07x preamp, both are warmish components.
The $1500 D-Sonic amp has a switch to select between RCA and XLR inputs. So I have the CODA and Topping preamps hooked up to it at the same time. The speaker outputs from the D-Sonic go into my RAAL SR1a headphones. I recently got an RCA cable to make this Topping to D-Sonic connection possible. So another listening option.
I do not plan on buying more gear after I get some speakers for my living room. I am pretty sure I will stick to what I have now built. This system setup was a long time in the making for me (about 10 years of saving).

A new update on my finalized office system. I now have the CODA #8 to pair with the CODA 07x or Topping pre90. The CODA #8 is incredible with the Thiel CS3.7. Better than the Benchmark AHB2, though I like the sonic signature of the AHB2 a little more. The AHB2 does not have the required power at 2 Ohm. I can see it makes a massive difference. I had to lower a Convolution filter I use in my small office to be ruler flat as opposed to the slight bass bump I was using with the AHB2 monos. These DSP files were professionally created for me and are of incredible quality.
The Benchmark stack is also super quiet while the CODA stack has a tiny bit of hiss with ear against tweeter (like most gear). This is not a deal breaker since the CODA pair sounds so good with the Thiel CS3.7.
I moved my AHB2’s to be the mono amps to my RAAL SR1a. It sounds incredible via the CODA 07x preamp and another RAAL SR1a Convolution file. It is not really overkill because these headphones can use the power.
Now everything is not unicorns and rainbows. My Topping pre90 and the CODA #8 sounds like crap, very disappointing on that. The Topping pre90 and AHB2 sounded great but I do not use that combo anymore to the Thiel CS 3.7. I need to figure out what to do there. I will likely have an orphaned KEF LS50 in the future so that is an option for the Topping pre90.
I was testing the Topping pre90 today with RCA sources, but XLR output to the CODA #8. Maybe that makes a difference because I compared the all CODA setup using all XLR’s.
I wonder how the Benchmark HPA4/LA4 + CODA #8 would have sounded (won’t know now). The AHB2 and CODA 07x are amazing together.
BTW - I only have the Benchmark DAC3B in the office. I had to move the Gustard X26 Pro downstairs to do preamp/DAC duties for a month or so while I get some cosmetic repairs done on an integrated amp. The DAC3B is great with the CODA stack. |
I spoke with my CODA dealer who sells CODA gear to a lot of recording studios in Los Angeles. He told me a few of his professional clients use the Benchmark preamp (LA4/HPA4) with the CODA #8. He thought the Topping pre90 sounding dull or lifeless with the CODA was likely an impedance mismatch.
I sold the HPA4 to some guy in France a few weeks ago but I only lost $200 so not the end of the world to buy the LA4 to replace it. Bye, bye Topping pre90 at least with the CODA #8.
I also learned that I could reduce the tiny bit of hiss on the CODA 07x preamp by lowering the individual source gain on the CODA 07x. I had raised it in the past to match the HPA4 sound level when I was comparing gear via ROON. |
