I moved from Adcom to Odyssey. If you want to continue the theme of a burly SS amp, the Stratos is a thought. I'm not sure I'd call it warm, but it is definitely not brittle like the Adcom; I'm definitely sensetive to fatiguing highs, and I happily lived with a Stratos for five years. A nice amp, and a definite step up from Adcom, with good values (and continued manufacturer support) on used pieces.
Best,
John
