    The Krell KSA-100 MK1 does not use sustained plateau bias, it’s a pure class A monster that’ll draw several hundred watts from the wall all day.

    Nonsense.

    I have a few of these door stops in the lab, in their day they were different, never saw what all the fuss was over unless you had Apogee's and need to power a dead short lol

    Unless you know the history of the unit then I would leave alone, also remember these things would use around around .5kw of power at idle.

    If you have a pure class A amp, it's best not to leave it on all day.

    Glad I didn't ask on here before I got mine. I fancied it so I just bought it.

    Seems to be some quite bizarre prejudices against Krell/ American muscle amps. Legacy of the UK flat earth brainwashing maybe? An amplifier should be able to deliver watts and current, if it can't it isn't actually very good. Of course it is expensive to make an amp like that, it eats into the profits, so instead let's tell everyone that there is something magical about low powered amps with saggy power supplies.

    a good analogy would be using a stretch limmo for the school run great amps but better used with speakers that need it. again imo.

    Jeez don't give the Yummy Mummies round here ideas. It's bad enough with wall to wall XC90s, X5s and the like.

    I'll be honest,

    The reaction to the Krell question has surprised me somewhat.

    Whether one Needs all that power really doesn't matter because most of us really dont. The only question I suppose is, does it sound as good when you aren't using it to its full potential. Being Class A, I don't see what reason there could be for it not to.

    I can see why a low powered amp may not be ideal with inefficient speakers but for what reason would a high powered amp struggle to sound good through efficient speakers?

    Apart from the quite frankly child-like remarks at times, the only comment of real value has been the effect heat can have on the life span of components.
