I am picky about this, any suggestions???

I am more than picky about this subject, I'm extremely picky. ( amps & preamps ) I would say try to keep it below $2500 used price each? Although I wouldnt mind hearing some suggestions in the $500 a piece range all the way up to $2500 a piece range( used ).

I dont know why I am so picky when it comes to this , I have tried Bryston way back in let me think, 1999? Maybe I need to hear them again? I have also heard aragon in 1999 to. It was the 8008bb. Dont remember which Bryston it was?
None of them sounded that much better to actually upgrade.

Let the suggestions flow!
Thanks for your time.
