McCormack makes great SS equipment. I'd second that amp reco. I can't second the Adcom. I don't care for Adcom sonics, and if they have reliability issues, why would you even consider it. How 'bout the matching McCormack preamp? What features do you require in a preamp? Phono? Remote? I own the VA Beethovens, I've found Classe equipment to mate well with them also. I've seen used Classe CP-50 preamps on the used market for $800-900. They are hard to beat at that price. If you crave tubes, I'd recommend an Audible Illusions preamp, you could grab an L1 for around $700.
Good luck, and enjoy the Haydns.
