I guess the greatest compliment a reviewer can give the manufacturer is to ask to buy the demo unit (with some aesthetic changes) and to even spend quite a bit of money on having a custom, higher-end, 6 foot cable built for it, and to get a second copy of Amarra 2.0 with the iLok dongle and everything to "process" the sound a little and control the MIDI settings, so the DAC knows it's getting a 24/192 signal (which I did sample and which sounded lovely).
So I suppose, to sum things up, despite a few minor complaints that really apply more to a $10K DAC, the Wyred 4 Sound DAC-2 can give you some very lovely sound with a minimum amount of effort and a true plethora on input choices and configuration options, like volume control and processing up to 24/192KHz files (automatically selected with Amarra 2.0, I add again). I thinkalthough it does have a bit more air and ambience and perhaps an overall more elegant design and user interfacegiven that the PS Audio PerfectWave DAC costs almost exactly twice as much as the DAC-2 (it appears to retail for $ 2999.99 commonly) and you can get the DAC-2 and put that extra $1500 into some bitching cablesI say go with the DAC-2. There's nothing wrong with the PerfectWave, and it has a slightly higher "Wife Acceptance Factor"; however, I could never find a filter on it that sounded quite right and quite honestlyI don't know what kind of filtering the W4S DAC-2 uses but, as Goldilocks said, "It's just right". Like I said, I'm buying the demo.
