I have compared at great length the Pass Aleph 3, Blue Circle BC22 and BAT VK200 and feel all three of these solid state amps may be a good candidate for you. Of the three, I feel the Blue Circle has the rounder, more "tubelike" character.
I own an older Bryston 4B which I use for my subwoofer and because of it's more neutral, grainier nature might not be what you're looking for. However, I understand that the newer ST and SST versions are much smoother.
I think a super bargain is the McCormack DNA 0.5 or 1. You might even be able to snag a Deluxe version of one of these for under $800.
I do think that the brightness you're experiencing may either be room related and/or attributed to the Denon receiver.
