I have been enjoying my Krell KST 100 since I bought it new around thirty years ago.
Bought at Sound by Singer (maybe from Steve Guttenberg?) on sale for $2450. Excellent amp. I’ve upgraded everything but the Krell over the years. I had it refurbished by the factory a few years ago. Great people and great service.
Does a terrific job handling bass. Clean mids. Strong points. Stereophile measured it at 135 watts per channel. They reran Martin Colloms review a while ago and I have to say I agree with his assessment.
