I’m a little confused. In your report it seemed like tube rolling switched component preferences, and combinations of component preferences. It makes more sense to me that rolling tubes in amplifiers, and then swapping amplifiers, should result in bigger sonic differences then tube rolling within a single amplifier.
Maybe i wrote about the rolls in too much detail and it got confusing. The Psvane lowered quality of the system, and Lyra sounded less good, kiseki better. With the RK 300b the Lyra sounded much better. Lyra also sounded equally good with the other valves, but the drop in performance was clear with Psvane.
Reasons for aesthetix sounding better had to do with a different step up.
