Love these old reviews, brings back a lot of memories of reading Stereophile and trying to figure out how I could buy some of this stuff. It doesn't seem that long ago. Seems there were a lot more reviews per issue back then too.

would not be acceptable in a $500 preamp, much less one that sold for 2 grand. Odd that Krell didn't have a manufacturer's comment addressing this. High quality controls with near perfect tracking were certainly available in the early '90s. Most Japanese receivers did far better than this.

You make a valid observation but it probably wouldn't bother me if I owned the piece, which, I did just look up on eBay to find one for under $1,000.

I was selling Audible Illusions PreAmps that had separate volume knobs for each channel, I felt it was a good design.

Krell is good gear, I could live with it.
