Having owned all of these products at some point in time, with the exception of the KCT, I would say the Krell (no surprise) has that iron-fisted bass like no other. Pass is very close, but not the same. The Pass has a slightly more organic character that I have not heard in Krell, but the Krell has better bass.
I own all Pass now. Sometimes I have a hankering for a Krell amp, who knows, maybe I will try another.
