I have tube rolled KT88 tubes in a Rogue Cronus integrated amp. I was unaware of Sophia at the time. I tried JJ Blue, PSvane Horizon, and Genelax Gold Lion. My conclusion was the Gold Lions were the most open , had extended bass and treble, and all round more musical than the other 2.
I have since bought a Primaluna EVO 400 and replaced the Primaluna EL34s with Gold Lion KT88 with the same results. Primaluna like Sophia tubes are made in China supposedly to their specifications and control.
My experience may not be the same as yours and nobody is right or wrong.
And my experience probably doesn’t matter anyway
I agree with @jbsqg, the preamp tubes are 75% of the sound. I only changed power tubes after going all NOS preamp tubes in both the Rogue and Primaluna.
