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

Ejif, The reason Krell told you to connect an earthnet cord to your amp is for them to evaluate your amp on their main server their at the factory, believe it or not, your amp is computer oriented, Krell can and will literally make ajustments to your amp if the fans are working out of the ordinary with the speed and sound of the fans, I would hook the amp up inside the house to the connection,you would have to be useing the amp at full campacity when you do this, call krell on the phone, and see what they do with their main server for your amp, it's like essentially your krell in the krell shop without ever leaving your house,and the connection tells krell if there is a problem that you have to send the amp to them for work done to the amp as well, Awsome to me!

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.

So if an amp can put out 100+ amp peak output then how does a typical 20 amp circuit respond to something like that?

ha,ha,That's a good question Ejif, +1 on this one.

Peak amplifier output current does not have to be less than the current of the circuit powering the amp. This is because power is equal to voltage times current, and since the line voltage (i.e. 120V or 240V) is in most cases higher than the amplifier output voltage more current can often be available at the output terminals to drive speakers.
