Whats the krell sound?

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.

I don't think it's correct calling Krell Bright! I've heard Krell sound bright in certain system combinations. But that goes with lots of gear combo's. The more analytical you get, the more things can tip "hot" tonally. It's a balancing act indeed.
As a line the Krell isn't bright though. I'd say it's good hifi effort, and better than most.
