David,
You're partially correct, software is part of the equation. Think of Vincent in the vein of a network communications firm. These outfits offer software, hardware, and professional services. They have channel partners and can usually offer packages for every budget, configuring everything in the process so that it is user friendly.
I was very impressed with the set-up. It was better than my CEC/Lessloss combo. More information, more relaxed, more texture, and better sound staging. For once I think I understood what is involved in not only digital playback, but studio engineering and recording as well, which ultimately is the process that gives us the music we listen to.
Steve - using my DAC with the rig was not an option.
Bottom line - I'm a believer in computer audio. I'll be listening to the Wavelength stuff shortly so that I can hear a USB solution. I will eventually get around to Empirical Audio as well.
Last note - we listened to the same recordings on iTunes and the VRS software. iTunes sounded broken. Unless I'm missing something I can't see how iTunes is a viable playback solution for high quality audio reproduction. A bedroom system maybe, but not a listening room.
