First System Amp . . .

evolving into Second System. My trusty Adcom 545mkII just died. It serviced Energy A5+2 speakers; an Adcom 500mkII serviced it. I won't describe the cdp source (embarassing); a remedy is in the works but not final. So where do I go from here? Any suggestions on a good replacement amp (there are SO many to choose from)? I'm looking for about the same power but perhaps a bit warmer sound. Thanks.
