I second what Dannylw and Edesilva said. When I got my Aeons, I looked at all kinds of amps, including the Parasound monos that have gotten rave reviews. They sounded nice, but when I hooked a Rogue 88 Magnum up to the Aeons they just bloomed beautifully. Stats are fast enough to overcome some of the traditional knocks against tubes, and I haven't lacked for bass at all in my system. Try some tubes; if you have the $$, the CJ Premier 140 looks like the bomb, and Sam, when he reviewed it in Stereophile 2 months ago, had it hooked to Quads.
