I think the Krell sound is typical high end SS. Very analytical, resolved, bass strong, perhaps a bit cool in palate, with a big soundstage. I also think the more expensive the krell, the more body you get to the sound, wiht a sweeter top end. However, you always get bass and control with Krell stuff..that's almost agiven.
In general however, I think typical Krell would compare against a more gernal romantic, euphoric, tube like, liquid, syrupy sound and such, which you might find from most tube gear, or SS with a fatter upper/mid bass and such.
Of course, this is my take. I've sold Krell over the years. And I find the midline stuff is descent, and the expensive stuff is much better. All in all, I like the line...especially the AV pre/pro's for movies.
