Zarathustra's picture

"I have recently found the Krell solid-state equipment to be particularly impressive, and there is one hell of a band of designers trying to make tubes truly obsolete."
Well Krell surely did not make tubes obsolete like Mark Levinson didn't.
Jeff Rowland and Threshold did a better job in that area.

I love the sound of CJ equipment but loath their build quality especially in the eighties. Premier One (b) amp still sounds great to my ears.
