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

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.

Bill_k, great explaination.

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...

I have the Krell Vanguard and my fans did go off in the summer but it's been all quiet ever since. It's smooth and very open sounding. The new Vanguard kind of reminds me of the Sim Audio I7 but less clinical sounding probably due to the class A design. They both have a lot of steps with the volume control.
If you like the Krell sound the new gear doesn't disappoint. Looks are just OK.

Thankyou Gold for your response here, the new krell equipment is still getting circulated to the users to give their opinions on the forum sites, give us more when you can, cheers.
