    I would imagine there are plenty of solid state power amps out there now that equal the Krell for sound quality and better its dynamic ability. I certainly know of a few but they are expensive. The Krell may turn out expensive if things don't go well.

    Do you need a power amp this big to drive your speakers?
    Certainly not Jim!!!

    My speakers are 98db sensitivity if I recall.

    I really liked what Macca's did at the Bakeoff and this one is available at sensible money. Do I NEED it? No, the Monarchy Audio SM-70 is killing it here. Do I WANT it? Not sure. The effort to get it to even fit in the room is almost as big as the amp and a few good points have been raised over its usage over the years with all that heat have hit home.

    I think I'll leave it and keep looking for another SM-70.

    thanks all.

    With 98db speakers, you'd probably get away with a three watt SET mate. 2A3 could be nice.

    I know I don't need a lot of power. I just caught a bit of curiosity after the bakeoff.

    I need another SM-70

    30W of Class A more than enough. I think the KSA-100 would be a mismatch with 98db speakers.

    You could be right actually.

    Almost all of that advice was terrible.

    1) if it goes wrong it won't cost any more to fix than any other amp
    2) It's designed to run hot
    2) it won't run hot into very efficient speakers in any case
    4) It doesn't matter how sensitive the speakers are, it won't be a 'mismatch'

    Years ago when discussing cars there was a saying that went "There's no substitute for cubes". I also think that there's no substitute for power. I absolutely love the slam and grip of big amps. Yes I know it is only loosely connected with power but these big SOAB amplifiers just grip the speakers to near death. Love that grip so much. Buy it..! Regret later; much later

    I could be wrong (it happens), but don't class A amps run hot all the time?

    The Krell runs in a slightly different class A set up to the classic notion of class A. It uses Sustained Plateau Bias which means it does not run as hot as a typical Class A amp.
    Main system : VPI Scout 1.1 / JMW 9T / 2M Black / Croft 25R+ / Croft 7 / Heco Celan GT 702

    Second System : Goldring Lenco GL75 / AT95EX / Pioneer SX590 / Spendor SP2
