State of the Source: Server, computer....or what?

Fla, their flagship model Antipodes "the Reference" appears to have a retail price at just below $7K. Perrotta Consulting is the only dealer listed in the USA.

Drubin, have you had a chance to hear the Baetis Audio server? Having lived with my mini set-up (which has a quiet fan) for awhile now, the fan doesn't bother me much (although I would rather they had passively cooled it) and I put more value in the linear power supply since I have heard the benefits of that with my mini. You may be onto something with their taking the SPDIF from the motherboard since the crappy USB is always mentioned as a drawback when discussing the mini as a server. Does the Baetis use a Linux operating system?

Surprising to me not a single poster has yet weighed in on their experience with digital sources. Back 5 or more years ago, when we were mostly spinning silver discs, the discussions on disc players seemed almost endless, yet now when probably about half the folks here are using a digital server type source (or computer) there doesn't seem to be the same level of discussion about sources, only about DACs.

I am genuinely curious about the new class of servers coming to market recently, why they are said by some to sound better than tricked out computer sources, and how they actually differ from a tricked out computer when that is exactly what they seem to be.

I am curious to hear from folks who have directly compared several of the available server options and what distinguishes products like Antipodes (that is getting good press lately) from others such as Music Vault, which seems to offer more bang for the buck since their comparably priced units have features such as SSD, fast processors, ripping capabilities, multi-TBs of of storage, and equal sized multi-TBs of auto back-up.

I do understand some of the server products utilize proprietary software but does that really make that big a difference, since a computer is able to run different player options that the user can download.

I guess I was hoping to see more technical discussion and user comparisons to understand better what design features have the greatest impact on SQ and how that shakes out with the different digital source options available today.

As I continue to research the potential benefit of a dedicated audio server, two reasonably priced options seem to be the Antipodes DXe at about $4,000 and the Aurender X100L at about $3,500.

In comparison, the Aurender X100L would seem a better option because of an internal 120GB SSD cache for "latency-free playback", and two onboard 3TB HHD storage drives while the higher priced Antipodes DXe offers only HDD storage, with 1TB for the base $4,000 price, 4TB for $5,000, and no SSD until you upgrade to their more expensive DX Reference model. On the plus side, the DXe provides "Internal Linear Regulated Power Supplies" and an onboard "Auto CD Ripper." Both offer quiet operation with no fans to be found in either unit.

The Aurender's "fanless Switching Mode Power Supply" that "delivers stable power to non-audio components" is disappointing since, to me, that may be the only poor design choice in the unit. Being internal, it would not be easy to replace with an outboard linear supply. Replacing it would require an operation like on my Mac mini, where the original supply is entirely removed and a jack added or, in the case of my mini, a hard-wired cord. Maybe they believe it is not a problem since although their next model up, the Aurender S10, uses a "low-noise linear power supply to effectively minimize jitter and noise," it also uses a "fanless Switching Mode Power Supply" to deliver "stable power to non-audio components."

If I were to purchase today, of these two, I would probably select the Aurender XL100L because the interface is supposed to be excellent and the combination of 6TB of on-board storage plus the SSD would be hard to beat...if it just didn't have that SMPS.

However, nothing I have read about so far compels me to purchase a server at this time, since either option seems to be a sideways move at best compared to my Mojo Mac mini set up, which already has an outboard 2TB AV HHD that is powered by the same linear supply that powers the mini, and that connects with the mini using a special non-powered firewire cable. Since my DAC has an internally powered USB input, I run the USB from the mini into a filter and galvanically isolated (ifi) power unit and then into the DAC using a non-power USB cable. By using Pure Music as a player, I can upsample to 24/88.2 (or whatever I choose) and playback from the SSD in memory mode, so the HHD is only used for storage. I suspect the reviewers who keep writing about computer sources sounding "thin," in comparison to audiophile servers such as the Antipodes or Aurender, do not have their computers optimally set up with linear power supplies, SSD and outboard storage.

I plan to keep looking but, at least for now, I am not compelled to give up my computer set-up for a dedicated server. Servers, DACs and computer audio have all made huge advancements in the past 5 years and continue to improve with each year's models eclipsing previous versions. That is another reason I am struggling with investing upwards of $5K on a new server at the present time.

I found the following quote from 6moon's Srajan Ebaen interesting, given that he has heard/reviewed several top notch servers and has been into computer audio for quite awhile now. Even more interesting since Srajan's computer is not powered with a linear supply, which I found to improve tonal density and dynamics.

But what I'd concluded after my encounter with Aurender's top €15'000 server became a syndication for the aria to have me quite unshakeably sure now. A properly configured top-drawer iMac—library on 2TB HHD; OSX and PureMusic & Co. on 256GB SSD; 16GB of RAM for memory play to spin down the HHD entirely; bypass of redundant processes; 64-bit software upsampling etc—still makes life for costly audiophile servers most difficult indeed. So far I've not heard a truly compelling sonic reason to join the seemingly credible but quite off-key chorus that computers are bad for audio. If you do it right, it just ain't so!

Vapor1, I did not intend to leave anyone out but Perrotta Consulting is the only USA dealer I found listed on the Antipodes website. Thanks for clarifying.
Have you, or any of your clients, compared the mid-level units (the DS Ref or the new DXe) directly with a well set-up Mac mini (e.g., linear PS, outboard HDD, inboard SSD, galvanic isolation of the USB line, and isolated USB power source not from the computer)? If so, what did you (or they) hear in comparison and, if the Antipodes server was preferred, what attributes, in comparison to the mini set-up, do you believe distinguishes the Antipoeds unit?

Igator, the top model Aurender W20 does indeed have a SMPS powering the CPU but also uses a LiFePO4 (LFE) battery power supply for the audio power supply.

Reviewers seem to like the X100 but a couple point to a lessening of the bass impact compared to their disc players, a deficit not mentioned in reviews of the upper two models, the older S10 or the newer and most expensive W20. Reading between the lines, I get the impression of a musical and enjoyable sound quality but not quite equivalent to the upper echelon of servers in the areas of resolution or dynamics.

Drubin, I have seen info on Baetis Audio of Montana and to me their product seems to have a lot going for it such as external file storage, an SSD and an optional linear power supply. Unfortunately, it also has a FAN, which seems to be a backward move.

Sheesh, can't these guys put it all together. It seems each of the current crop of servers below $5K has one drawback;
-Aurender X100 with their SMPS,
-Antipodes with their single drive and no SSD option, and
-Baetis with their fan.
I like the concept of the Baetis but it seems little different than the CAPS servers offered by Small Green, and barely different in function from the Mac mini server I am running now, except for the Windows vs. OSx differences.

One reason why I haven't received more responses to my recent music server threads may be that not too many here use purpose built music servers.

Out of over 5,000 virtual systems listed on this site, I found 136 systems (less than 3 percent) using a Mac mini as a music source/server, and only about 60 systems (just over 1 percent) using one of the more common purpose built music servers, from the manufacturers listed below;

- Musica Pristina
- Baetis
- Aurender
- SOtM
- Antipodes
- C.A.P.S. (Small Green Computer)
- Mojo Audio
- Core Audio
- Olive
- Bladelius
- Naim
- Lumin

FWIW, about half of the 60 servers were from Olive.

I obviously did not search for all brands of purpose built music servers, and I am sure many here are using either a variety of streamer choices, a VortexBox, Mac books, or PC computer sources to play music but, based on the brands I did search, the purpose built server just doesn't seem to be that popular yet, at least based on the posted systems.

Maxboy00, I didn't include Music Vault with my initial searches and there were indeed 3 Music Vault servers that showed up in Virtual Systems here, which is still not statistically significant (e.g., results in 1.2 percent using purpose built servers).

All of these servers have their supporters but, without enough folks here using them, there is not enough general feedback to have a clue as to how they might sound relative to each other, or relative to a tricked out Mac mini or C.A.P.S. server.

Most of the reviewers who are comparing the purpose built music servers to computers are not comparing them to the C.A.P.S. servers or Mac minis that are optimized for music with SSDs, outboard HDDs and linear power supplies, plus measures to clean up the USB output such as filters, galvanic isolation, and elimination of the power side of the USB cable. As a result, "buy to try" seems to be the only way to hear how good those music servers sound.
