Why do you keep assuming I've used a passive? I never have and I never will. I find it ironic you're sitting there deriding gain in a pre-amp which is almost certainly going to be of a higher quality than gain in a power stage. This is like your silly claims about the superiority if BJT's. It's like you don't have a clue what you're talking about. It hardly matters what the beginning impedance of the pot is because when you open it up it's going to drop massively. Is 2kOhm good for anything? That's the whole problem you can't seem to see. You turn the thing up and now your source is seeing a very meager impedance and your amp is still seeing a relatively steep impedance, the kind you just called "unacceptably high". It all over the map depending on where you put the volume. How are you not seeing that????
