As a bookend to the above post, I ended up getting a DAC2 HGC and have been listening to it for a while now. This is a superb unit that has exceeded my expectations in every way. It is exactly what I was looking for. It allows my 805D2 + REL S/2 to show what they are truly capable of, simply stunning. IMO it does everything right.
I am very, very pleased with this unit. To me, it is worth every penny.
