In every case where I have tried two lesser quality amps as opposed to one higher quality amp, the single, better quality amp has outperformed the pair. I would recommend finding an outstanding stereo amp. Get one with vastly higher power, and the presentation will radically change for he better.
converting stereo power amps to mono
I will shortly have one superfluous Sonance 260 from one system and no amp for my Chapmans in a separate systwm. Am I better off dropping the Sonance and looking for a $3-500 dollar power amp or picking up another 260 and figuring out how to convert them to mono power sources?
