Why do these Zyx Fuji and Airy 3 have such a dark sound?


Hi everybody.
I only have around 24 hours for this, so I’m posting this last minute. Sorry about this. I’ve also posted this on Vinyl Engine.
Before I go into details, this is my question:

To anybody who owns a Zyx R100 Fuji S or a R1000 Airy 3 X (or similar models), does your cartridge sound "dark" like I describe below (a big dip in the treble)? Sound clips are provided at the end.


Okay, here I go. This is long, so I hope you can cope with all the details, as they are necessary:

I have these two cartridges on loan (and I have to return them tomorrow) because I had previously downloaded vinyl rips done with these two carts, and I really, really liked the sound of those vinyl-rips. The carts seemed quite accurate and neutral and as if they had a fairly flat frequency response and without harshness, which is what I was looking for: Not a "typical" dark MM sound, nor a "typical" bright MC sound either.

So, this is where the trouble starts:
The downloads don’t sound like the recordings I’ve made myself with the same carts! Some people call Zyx carts too bright, but it’s as if the treble is missing on my recordings when I compare to the downloads. It’s possible that I just don’t like these carts after all, but it’s strange that the downloads all have the same sound signature even though they’re from different uploaders using different systems, which would indicate that nothing would have gone wrong in the recording or uploading process.

I think there are four possible explanations to what I describe below:
1: My recordings sound like these carts are supposed to sound like, and I just don’t like them.
2: Something has gone wrong in all of the downloads I mention.
3: None of the phono stages used for the vinyl-rips I mention follow the riaa curve, but are all top-heavy by several dB.
4: All three Zyx carts (yes, three, see further down) are faulty

So, I’m wondering if I’m doing anything wrong, or I can adjust some settings to achieve the same sound as the vinyl-rips I downloaded. I feel like I have literally tried EVERYTHING there is to try. I read that Zyx carts are very sensitive to setup, but no matter what I’ve done, the sound hasn’t changed, except for a slight change in channel balance. I’ll elaborate about this further down. One thing I did notice was that both the Fuji and the Airy were very loud when I stood next to the turntable and listened to them play "acoustically".
Yesterday, I took the Airy to an acquaintance’s place and tried it on his turntable, which was an old Thorens with a Mørch UP4 tonearm. He used PSB Imagine T2 Tower speakers. We both agreed that the recordings done on my setup were identical to how it sounded on his setup, except maybe that there was a slight speed discrepancy.

Here I can also interject that I’ve also been trying out a Goldring 2500 cart at the same time, and that was too bright for me, and even brighter than certain digital 16/44.1 kHz masters that the records had been cut from. So trying that cart, as well as trying the Zyx on my acquaintance’s setup, would rule out that there’s something wrong with my turntable or preamps.

And the last aspect that can rule out that my equipment is the problem is this: Before borrowing the carts, I went to the shop and made a recording (with my own phono preamp with its built-in convert) of the new Zyx Ultimate 100 on their setup, which I’m quite certain was an Acoustic Signature Wow XL or XXL turntable with an Acoustic Signature TA-1000 tonearm. That recording was even darker than the one done with the Fuji on my own setup. The shop also said that the Fuji was a bit brighter than the Ultimate 100.

I use my headphones and Foobar’s ABX plugin to compare my own recordings with the vinyl-rips I downloaded, so even if my headphones were broken, I would be able to hear the difference between my own recordings and the downloads (like I could at my acquaintance’s place yesterday).

Here’s my setup:
* Sennheiser HD650 headphones
* Rega RP3 with an RB-303 tonearm (2013 model)
* NAD PP-4 phono preamp
* Parasound Zphono preamp
* Also a Soundsmith MCP2 MC phono preamp with adjustable ohm loading that the shop lent me. I’ve ONLY used this on the Airy. When loaded with 100 ohm, like the NAD and the Parasound, the only difference I could hear between the Soundsmith and the NAD, was that the Soundsmith was a bit darker sounding. The Parasound is also a bit darker than the NAD. Feel free to read the excellent measurements of the NAD PP-3 on Stereophile’s website. The maximum deviation from the riaa curve is 0.25 dB. When increasing the ohm load to 1000 ohm on the Soundsmith, the treble became more prominent but still not to the same extent as on the downloads. After 1000 ohm it didn’t seem to change any further. At 10 ohm I didn’t hear any difference to 100 ohm. It just seemed strange to me that I had to increase the ohm load that much, when 100 ohm is the standard and when I read that people use less than that for Zyx. Also, the phono stages used in the downloads are not all able to even go to 1000 ohm (nor was it mentioned that the ohm load was that high). I am of course aware that comparing to a random download is not the perfect way to do it, but still… As mentioned, all the downloaded vinyl-rips have the same sound signature.
* Focusrite Scarlet 2i2 A/D converter
* Objective2 + ODAC headphone amp and DAC
I’ve recorded with both the Focusrite converter and the built-in converter in the NAD and I couldn’t tell them apart in an ABX test.

So, these are the settings I’ve been experimenting with:
* Protractors: I’ve printed three protractors: The Baerwald and Stevenson protractors from Vinyl Engine, as well as the Arc Template Generator that Conrad Hoffman made (I used Bearwald for that one as well). I couldn’t hear any difference on any of them, except for one recording with a slight difference. I’ve also tried pushing the cart 1 mm forward or 1 mm back, pushing it all the way forward into the headshell or pulling it all the way back, turning it a bit towards the spindle, or turning it away from the spindle. It didn’t make a difference except for a bit on the channel balance. With my Rega Exact cart I passed blind tests between a Baerwald adjustment and the "factory" setting with three screws (the Baerwald was brighter). In the shop, they adjusted the Ultimate 100 with a Dr. Feickert protractor.
* VTA: I could hear a small difference, but big enough to pass a blind test, between a recording where I raised the arm 6 mm, and one where I put two records beneath the mat, so it would be very much tail down. However, not much of a difference. I also heard the same difference with the Goldring (raised was brighter).
* Counterweight. I’ve tried going from 1,50 grams up to 2,50 grams. I’ve tried Art Salvatore’s recommended 1,85 grams, the recommendation of 1,95 grams from another, 1,79 grams, and pleeeeenty of other combinations, but I would mostly use 2,00 grams. No difference.
* I’ve tried to loosen the screws that bolt the cart to the arm a bit. No difference.
* I’ve used a bubble level to check azimuth (I then adjusted my arm a bit). No difference.

Lastly, you might think that the carts just need to break in. I thought so too, although I’ve always been a bit sceptical about break-in. Anyway, the Airy already had some play on it, and I was actually given another Fuji to try out, and it was well-used, but that one sounded even a bit darker (just worn, really). On top of this, the way I understand break-in is that before a cart is broken in, it will sound harsh and bright – the opposite of what is the case here. But if Zyx carts get a more prominent treble after breaking in, if breaking-in even exists, then this could be the explanation.

So, on to the sound clips:

I have uploaded the following clips recorded with the following equipment (all of my recordings are done with the Focusrite converter), and yes, the albums are all the same editions from the same countries (I always make sure of that):

1: AC/DC "Rock or bust", done with my Rega, the NAD preamp and the Zyx Airy, then the same setup but with the Soundsmith set to 1000 ohm, then the CD, which I believe is the same master used for cutting the record, then the vinyl-rip that I downloaded, which sounds quite close to the CD, done with the following equipment: Micro Seiki DD-8 + ZYX R100 Fuji S, PS Audio GCPH Phono Stage + Tube Preamp (Telefunken tubes 3xE88CC), TASCAM HS-P82. Lastly, a vinyl-rip download to compare, recorded with a Micro Seiki DDX-1000 / Micro Seiki MA-505L, Benz Micro Ruby Gullwing SHR, Past Audio C-7Super (Deluxe Edition), and M-Audio ProFire 610.

2: Marilyn Manson "Deep six" (from "The Pale Emperor"), my own recording with the Airy and NAD, then also with the Zyx Fuji and NAD, then done with my Rega Exact cartridge and NAD (I did, however, adjust the channel balance on my computer, as it was off, partly because the cart was made that way, and partly because the arm on my own turntable at the time was not mounted completely straight), then the recording from the shop done with the Zyx Ultimate 100 and NAD (detailed above). I had to adjust the channel balance here as well. And then lastly two vinyl-rips I downloaded, done with the following: 1: Pioneer PL-7L + ZYX R100 Fuji X, PS Audio GCPH Phono Stage + Tube preamp + Tascam HS-P82. 2: Garrard 401, ZYX Airy 3, Trilogy 907, Korg MR-1000. These two downloads sound quite similar.

3: Chris de Burgh "Take it to the top" (from "Man on the line"), my own recording with the Airy and NAD, then a vinyl-rip download done with a Garrard 401, ZYX Airy 3, Sentec/Nebula (A), and Korg MR-1000.

4: Queen "Self-titled" (re-release on Fame) my own recording with the Airy and NAD, and a vinyl-rip download done with Garrard 401, ZYX Airy 3, Sentec/Nebula (A), and Korg MR-1000.

5: Mastodon "Black tongue" (from "The Hunter") my own recording with both a Fuji and an Airy and the NAD, and then with an Airy and the Soundsmith set to 1 kOhm, and then a vinyl-rip download made with Micro Seiki DD-8+ZYX R100 Fuji SH, PS Audio GCPH Phono Stage + Tube Preamp (Telefunken).

LASTLY, since I figured that most of you wouldn’t have any of these albums, I have included recordings of two albums you might have, so you could compare:

Dire Straits "Brothers in arms" and "On every street" (both original EU prints).

I only have my own recordings of these, but I know that they’re both cut from digital 44.1 kHz masters, and my recordings are not very close to the CDs. The Goldring cart was brighter than the CDs, since it seemed to have a big spike in the treble.

So, here are the downloads:
https://mega.nz/#!dMZzmQxL!NnJaOtkx281lunKjeRpwSTmkKa8CUYuaEoVehKiyy-k

I hope this doesn’t sound offensive, but I’ll just say this to avoid any potential arguments and that people waste their time writing a lot of things: As you might have noticed, I’m a no-nonsense guy, so please no suggestions like "digital is crap", "you’re deaf", "buy a different turntable", or "buy brand X phono stage" or "buy new interconnects" or "buy a Nordost power cord" or "these carts are not good for that type of music" or whatever, because it’s besides the point, I’m not going to buy any of that, and I’m not I even going to debate it.

Anyway, I appreciate any and all help :-).
Thanks, and thanks for reading through all this!

"I read your post and came to the same conclusion that seems apparent to everyone."
That I just don't like these carts?
If so, then I concluded the same, but I'm still wondering why all the downloads then sound different, and why they all have the same sonic signature, since it would be strange if something had gone wrong in all those recordings + Zyx doesn't have a reputation of making dark sounding cartridges.
Anyway...
Do you always use this strange method to chose the cartridges ? 
It reminds me people who judge audio equimpent by youtube videos.

Cartridge in the actual system is not exactly what's on your digital recordings in the headphones. Maybe something wrong with your recordings, who knows, how could this be a reference?  Maybe you need a better headphones or better headphone amp, or it's about your hearing abilities or personal preferences and experience... or something else.  

Do you like digitaly remastered records? Maybe your LPs are not the best quality? Afterall everything depends on the LP first. The best souding LPs are mastered from the mastertapes or in real time with direct cut and this is where the magic begins!  Digitally recorded music must be better on digital source, i don't understand why people needs an LP cut from the digital master? 

If you had ZYX there in an article in the manual about analog reproduction. I'm sure the best way for you is to check your next cartridge in the actual system and not bother about all these perversion to make a digital copy of a digital master cut from vinyl to compare it to another digital copy made by someone else. 

I just don't get why not just play a perfect analog recording (with no digital in the chain of mastering process) with some nice cartridges in a good analog system with louspeakers (not headphones) in your actual listening room?     

But the more important is to compare new cartridge to some nice cartridge that you already know very well. Advantages or disadvantages must be obvious if you have no limits with phono stages/tonearm matching. 

Don't know any person who can say the ZYX cartridges are "Dark Sounding". 

Maybe you prefer digital to analog ? 
"Cartridge in the actual system is not exactly what's on your digital recordings in the headphones."

Yes, it is. Analogue to digital conversion is completely transparent within audibility. Although I use the Focusrite now, I've even run a long, cheap phono to mini-jack cable from the output of my CD player to the line-in on my old computer with a $50 soundcard, recorded a CD, then ripped the same CD on my CD-rom drive, adjusted the volume levels and done a blind test, but couldn't tell the recording apart from the original.
And similar tests have been done several times with the same results. Digitizing something doesn't change the sound of it.

And how many times do I have to repeat that my amp and speakers are in storage, so I can only listen through my headphones?!
To quote the late Christopher Hitchens: "It has made me think I could write a sequel called 'How some [audiophiles] apparently can't even read'".

And there's nothing wrong with my headphones. Even if there were, I could still hear the difference between my own recordings and the vinyl-rips, as I also stated earlier.

You don’t have to repeat that your system is away, but it is so strange and sounds like you’re looking for the cartridges for your CD rom.

Why do you need an expensive cartridge if you can’t hear the difference between your digital copy and true analog records ? Please find a nice original LP from the 70s or 80s mastered from the tapes, then buy a digitally remastered reissue of the same record pressed nowadays, then you can make your blind test, but with the vinyl. Then you can tell us what you like the most. Even at professional studios they can’t reach the quality of the original pressing if the original mastertape is missing or unavailable. But seems like you can, even with your cheap soundcard using CD-Rs. Now please tell me why a copy from the original pressing is not a good source for reissue, why people like Analogue Production always looking for an original mastertape to make a proper reissues? Why do they need super rare mastertape if they could just rip the original vinyl in mint condition for the reissue? According to your logic there is no difference between a digital copy and the original. This is the biggest mistake! Why musicians still using a mastertapes in the studios if the digital is much cheaper? Because this is analog and you can’t get same quality from digital. Why the best mastering engineers in the worls still use 100% analog mastering if they could simply convert everything in digital and use computers and waveforms on the screen? Becase this is analog and you loose something when it became digital. Doesn’t matter for you? OK, i think you will be happy with digital and it will save you a lot of money if you can’t hear the difference in your system or in your headphones.

Audiophile with a "system in the storage" should put the system in the listening room first and then look for a components for the system, but not vice-versa. You can’t chose a cartridge by youtube videos or vinyl rips.

I also use Sennheiser headphones, but the music in my system with full range drivers of 101db is another world, completely different experience when it comes to cartridges.

The prove of your wrong statement is that ZYX is not dark souding cartridge, it’s the opposite to the term "dark" or "warm". The bass and highs of ZYX are extended, plenty of details, great imagind and 3D soundstage, i know this for sure about the Airy III model. I’ve heard dark sounding cartridges, definitely not ZYX Airy III. As i said earlier, if you can't get the LOMC sounds right then it will be much easier to get MM sounds right. 
OK. So after listening to several different tracks that you made available for downloading I'll make a couple points.  First, Mastodon rules!!! Second, I think that the Airy and Fuji are sounding pretty close to the way they should.  This is not "dark" sounding to my ears compared to the CD rips.  It actually sounds a lot better to my ears than the CD. The ZYX cartridges have a house sound of "ultra-smooth", for the lack of a better term.  I hear this in your rips. So its not that they don't extend full frequency, but rather they don't emphasize the attack of the notes and they loose a bit of the dynamics you might like to have with rock music. I was focusing on the drum/cymbal sounds and guitar primarily. FWIW, ZYX cartridges truly shine in their 3D presentation and imaging and I don't think that one can appreciate this character as well in headphones.

I do think you would be able to coax out more dynamics and some attack by pairing them with the right tonearm and getting the VTA and VTF just right.  But, as @chakster has mentioned, you might have a better time with other LOMC (Lyra comes to mind) or a great vintage MM.
