This is very interesting to me also. I've decided to get a Denon reciever and I've been debating between a lower end model such as the newer 1905 or the 3805 beauty. The 3805 is gorgeous but has power and connections I just don't need or will use for sometime. The only reason I'm considering the 3805 is sound quality.
So from what you're saying then JohnK practically speaking all DAC's are equal and I would gain no improvement in sound by going with the 3805 as opposed to a lower Denon Model?
Thanks again for posing those links guys, truely interesting.
