Hmm. I have a Freeway also, and I have heard it driving Empirical's Turbomod Perpetual P3 DAC.

Which VRS did you demo? (Platinum, Gold, etc) and are you running the Foobar via ASIO using 24/96 upsampling?

  The VRS Audio system I have heard is an early model. It was made before VRS had the 3 options. I believe it is very similiar to the current Revelation Gold.

  I'm running Foobar with ASIO output and 16bit fixed output. I use the Perpetual Tech P1A to interpolate and upsample to 24/96. I tried using Foobar to do the upsampling but it seemed to me that the P1A does a little better job. It just sounds smoother to me using the P1A to upsample.

  I'm on the short list to demo the Empirical Turbo Mod P3A. What did you think of the unit? I have read that most people who have the Turbo mod P3A find they dont need/want their P1A's any more for upsampling or jitter correction. Any thoughts?

    Steve's P3A is a fine unit. It's quite an achievement, really, coming from the rather old, stock P3A. Very finely graded resolution, better detail, refinement, and SLAM. Only roadblock is the price, but you know how that goes..

    Haven't A-B'd P1A vs. Foobar upsampling into Turbomod P3A, but since I find ASIO resampling to be plenty smooth (internally to PCI, though), I suspect you won't need the P1A. You'll find out, I suppose.

  Great post and thanks for sharing. You have a very nice system, particularly with the SET amps paired to Caine and Caine speakers. Excellent combo in my opinion for SET based system.

  I have heard an early version of the VRS system - not sure what version, etc. - but it was in my own system and I was IMPRESSED. It provided an extremely musical and 'live' presentation.

  I am personally trying to decide however, if this is the best approach or if it makes more sense to get the digital signal out of the noisy environment of the PC prior to D/A conversion, etc. In this regard, I am inclined to prefer the use of a computer-based music server as just that, a server, with digital data being output to a good D/A device.

  Steve's work is interesting and USB seems to be a very viable means of data transmission. I would welcome others' experience with this form of digital 'link', vs. SP/DIF from soundcard, etc. The real issue here is clocking and jitter of course.

  Thanks for sharing your experiences.

    Personally, I don't buy the harsh environment idea.

    Sure it is dreadful for audio in theory, but some sound card manufactures are good at working in this environment.

    How could you be impressed if the environment really affected the signal?? Obviously the VRS system is able to handle this "harsh environment" quite well....
