When I had my Khorns, I went from solid state(ugh), to Welborne Laurel 300b's, to Welborne Moondog 2A3's, then to Welborne StarChief 45's with Emission Lab tubes, and I was done.
The purity of sound was sublime. I had my stereo club over and everyone was amazed that I was using less that 1 watt. Midrange vocals, especially female vocals are to die for. Truly holographic. I still have the Laurels and the StarChiefs but am using KT120's to push my Tekton Double Impacts. I can't bring myself to get rid of these amps, especially the 45's.
