Classe does not support servicing of its older gear, in particular the products manufactured before the 2001 B&W acquisition. I had to throw away a tuner and a stereo power amp due to poor service support. You can buy older gear for cheap, but if it develops a problem, do not think that it can be fixed.
In contrast, I had excellent service from Pass Labs for an old stereo power amp. And I had great service from Audio Classics for an old McIntosh tuner. I have no experience with the other brands you mentioned -- Krell and Rowland.
