I've had the Totaldac USB cable playing for 30 hours straight. The improvement in sound quality on my computer audio is significant. All edginess in the treble that I was experiencing with the WW Platinum 7 is gone. I would characterize the Totaldac's sound as smooth, warm, rich, organic and incredibly musical. The soundstage is significantly larger and images are more holographic than the WW. Bass is rounder than the WW but still very pleasing. The Totaldac is very transparent with just slightly less detail than the WW. Images on some material are more forward than the WW. Listening to the Totaldac reminds me of listening to vinyl in a terrific analog system. In my mind, it's a knockout. The Totaldac USB has transformed computer audio through my Mac Mini. It is my new USB cable.
