Another vote for the AKSA... however, tube-like isn't my first choice of description... it's more nothing-like. Compared to the Odyssey, I guess it's tube-like in that it doesn't have a signature. It doesn't sound like tube or SS to me, it sounds completely uncolored. I have a tube preamp, SS DAC, and Revel F30 speakers. I'm happy with the great match.
The AKSA doesn't meet your original power requirements and it's not perfect for all speakers. Plus, it's tough to find an audition. Plus, even if Hugh builds some part of it, you still have a lot of custom work to do. (If you like that kind of thing like me, you're in luck, if not, another strike against the AKSA.)
I was originally looking into the Pass Aleph and Threshold Stasis amps which brought me to Hugh's products. Actually, Rod (Rocket) helped as well. However, after reading Hugh's design philosophy and the background of the design, I was sold. The AKSA is a high-current, very fast amp that delivers as fast as it can suck power out of your wall. A good power source is mandatory to hear the sonic benefits of the AKSA.
Good luck with your quest.
