It sounds fantastic.... but I'm not sure why. (I'm struggling to type with a squirming baby on my lap!) It's produces a vibrant, detailed sound without being too toppy. I noticed a big improvement over its predecessor, a NAD 3020a. It's plugged into a Dacmagic and a Squeezebox. As an experiment I used the balanced XLR output and one of the rca ones. When I toggle between the inputs there seems to be a slight difference in the stereo imaging... not sure why. Apparently the xlr inputs are one of the few tings CA changed on the V2.
I had it running through some really old B&W DM110 speakers, and it produced a fat warm sound. changing to the EB speakers, at first I thought it was too clinical a sound, but now I would describe it as crystal clear. It seems to be a combination that works well for me. Yesterday I had a mate over, a jazz fan and a bit picky. I put on Too Shy by Kajagoogoo (on an 80's electronic anthem cd) without telling him what it was. He agreed that regardless of the music the sound quality was amazing.
I'm pretty happy with both the amp and the speakers.
