SOtM USB Card
« on: 6 Apr 2012, 12:18 am »
OK, I have finally gotten around to finishing building the CAPS v2 server I bought from JDUBS a while back.  It was all set up except for having an OS loaded and the SOtM components installed.  Win 7 I got super cheap since I'm a student (working on my Masters), and so I got the server up and running before the SOtM parts came it. 

I have to say, even without the SOtM parts, the CAPS v2 was a BIG improvement over using my laptop as my music server.  Not quite as big an improvement as room treatments made in my room, but close!

When the SOtM parts showed up, I was able to install the SATA power filter inline with my SSD drive immediately, but I didn't have the right adapter to install the USB card.  The SATA filter was kinda meh.  Maybe a bit of improvement, but it was pretty damn small.  For $70, it's OK, I guess.  Made me a bit worried about the USB card being worth it, since it was over $300.

Got the adapter in to day and dropped in the SOtM USB card right away.  Everything went without a hitch and all the drivers loaded automatically.  Nice.  Sound?  OMG, it made a VERY LARGE improvement.  Probably a bigger overall improvement than going to the CAPS server made in the first place. 

Lets put it this way - my standard rez music now sounds as good as my hirez sounded from my laptop.  And the hirez now sounds a lot like very good vinyl.  Hard to believe, I know, but there it is.

If you are doing PC based audio, you owe it to yourself to check out the USB card at least.  If you have a noisy, non-dedicated music server, then the SATA filter might make a bigger difference for you than it did for me.  For $70, it's cheap/easy enough to try out and see for yourself. 

Anyway, listening to Gergiev conduct Prokofiev's Romeo and Juliet Ballet with the London Symphony Orchestra - wow!  Impressive space and dynamics and super smooth and solid tonality.  Earlier I put on the CD that has the lowest intelligibility of any of my CD's - 50 Cent's Get Rich or Die Trying.  Most of the lyrics are incomprehensible.  Or, they were before.  Now I can make out every misogynistic and machismo-soaked syllable.  Impressive!

I have a dedicated Sonore server (sonore.us).  Jesus just sent me a new (larger) case and SoTM card.  The standard USB output of the motherboard was excellent, handily outperforming any of the Mac based solutions I've used (Mac Pro, Mac Mini, and Macbook Pro), and any of the software I've used including Pure Music (also Audirvana, Decibel, Bitperfect and Fidelia).

The addition of the SoTM card took my playback up another notch.  The improvement in clarity and presence was not subtle.  Highly recommended!

Tyson, great work.  I have the SotM USB card in my Auraliti PK90USB and it is an amazing card.  Demian is sending me a beta or newly finished version of the linux image with DSD!!  Yes!  This way I can compare to native DSD (Meitner MA-1; my other DSD DAc, the Mytek, is not Linux-friendly USB class 2 audio via USB, only firewire)) via my Mac Mini, and I think the combination of MPD Linux, the SotM card and a Paul Hynes custom power supply driving the PK90USB should be quite amazing.  Will report back.

Ted, do you know what version / custom MPD kernel Auraliti is using to stream DSD? 

Could be a cool solution, especially if it can be "replicated" with an off-the-shelf Alix (super cheap).

I can see this USB card making huge differences when feeding USB DAC's that use USB BUS power and is not asynchronous, but it's beyond me how it would greatly help asynchronous USB DAC's that do not use USB BUS power nor depend on the clock from the computer.  I suppose I have heard more inexplicable things in audio  :scratch:

Mine's feeding an Empirical Audio Off-Ramp 3 with linear power supply, and the OR3 does not use USB BUS power.  It's not asynch, but I don't see how Asynch would matter anyway.  The card is about clean power and isolation from the motherboards USB bus.  Seems like any USB based audio system would benefit from that.

Tyson,  I'm planning to use the SOtM USB with an Off-Ramp 3 w/Superclock4 after a music server rebuild.  I asked Steve Nugent about it and he said it was worth a try.  How has your experience been?
