If you are picking up Revel Concerta M12 speakers I would not go for Odyssey or Musical Fidelity. I still have a Adcom 545 in my home studio. I have owned the Odyssey and my bro-in-law owns MF stuff. Both of these will be too bright for those speakers, although they are both excellent amps, but not for your setup. I would get a warmer sounding amp like a used CJ MF series, The McCormack stuff, Classe, even the newer Adcom 5802 will sound much better and warmer. All of this stuff can be found used under $1K. Any of these amps will be a BIG leap over the Adcom 555MkII (and my Dad owned that one)!
Not to sound like a saleman, I will be selling my CJ MF-200 soon on Audiogon, and that would work for you also.
