I wish I could say all amps, receivers etc sound the same, it would make life easier, but in my experience especially with Klipsch Chorus II's and Quartets and various Magnepans I can always count on the amp/receiver to have an effect on the sound. I loved the looks of my (both now departed) Proton AA-1150 and D-1200 amps with the big beautiful green power meters but not the sound compared to others. And there were others that failed to impress, mostly forgotten now, guess I'd post this just to have an excuse to show off one of my favorite looking pieces of audio art.
