Krell Duo 300 compared to Evo 302e or 402e?


Hi I am looking for an amp to power some Revel Salon 2s and wondering about these amps. From all I can read it seems that the 302e or 402e would be a good amp for the Salon 2s but the new Duo 300 with it's cooler running demeanor is definitely appealing. I am wondering if anyone out there has compared these or owned both and can shed some light on this?

I have the same speakers. Salon 2s are absolute current pigs and your amp is pretty light in that department with only 17 amps peak output, so I'm not surprised it heats up enough for the fans to come on when you are cranking the tunes.

By way of comparison, I went from a Plinius SB-301 stereo that could do 100 amps peak to Symphonic Line Kraft 250 monos that have even more current. I think I read somewhere they can do 150+ amps peak; although the manufacturer doesn't provide a number for them one of their lighter models pushes out 120 amps peak. In any event, they look like a late 60s muscle car under the hood and have lots of current to tap.

The Plinius had huge heat sinks and dissipated heat that way rather than through fans. It would run quite hot even though it was Class A/B, but the Symphonic Line amps don't even break a sweat at utterly ridiculous volumes, i.e. in excess of 115dB peaks.
I don't know how a 20 amp circuit would work. My monos are on separate dedicated 30 amp 240V circuits.

I'm also guessing that an amplifier's peak output is based in part upon the capacitors' ability to store electrical energy, but I am no electrical engineer...
