Is my Amp OK?

It is well respected, measurements here: https://www.stereophile.com/content/bel-canto-eone-ref600m-power-amplifier-measurements
The question is: will you hear a difference (and is that difference an improvement)? My guess is that if you compare them under controlled conditions, you will not hear any difference, and that is how it should be: straight wires with gain.

Any opinion on Cary Audio SA-200.2 power amp?

Would this be a step up compared to my Rotel RB-1590, or just a lateral move? My speakers are Revel f208 (just as a reminder). I am using the Cary DMS-500 DAC / Streamer on that setup.

Thanks!

More expensive things always seem to sound better, even if they don't. Also, sometimes things that measure badly sound great anyway (single ended amps…I own one with no specs anywhere, unless Dennis Had talks about one). To sum up: Don't listen too hard to anything, just get expensive stuff even if you don't really have to.

@wolf_garcia  that's a very interesting perspective! I like it!
