But they sound so fantastic! So what's going on?
If i understand correctly, mu is just gain right? I can't see variable gain being a problem, surely if it was up and down all the time i'd notice the sound getting louder and quieter constantly?
I don't know how all this stuff works exactly, but i imagine the variable mu only kicks in when the input to the tube is changed, either stronger or weaker, i don't think Schiit would build an amp where the signal to the tubes is all over the place
I'm probably getting all of this wrapped around my neck, but the PCC189's i've used thus far sound fantastic to me, excellent detail and expansive, sound better than all other tubes i have/had like RCA 6BQ7A, GE 6BZ7, SEL Lorenz PCC88.
Should i just stick with what my ears are telling me?
