My journey in the last few years has been BHK, replaced with Rogue RP7, replaced with ARC 6SE, finally replaced with Backert Labs Rhythm.
The BHK sounded best with 6-7 volt tubes, but was noisy with them in my admittedly overpowered system.
The Rogue was nice but I wanted a bit more resolution.
The ARC was hard and aggressive sounding.
The Backert is wonderful! Perfect balance of warm, resolving, no issues, only two tubes, responds well to tube rolling, including 12sn7 with adapters.
