Amp/Preamp Asylum Looking for a new Amp or Preamp? If you're after tubes, post over here. |

We know it's inefficient - of course. But does this inefficiency come with a SONIC penalty?
This is what I mean: The inefficiency of high bias requires *more output devices* for equivalent output power. There's really little doubt that increasing the number of output devices has some sonic penalty; there's a reason why both tube & transistor amps with a single pair of devices per channel are known for sonic purity. (Sure, extremely close matching of devices may reduce the penalty to zero or near it, but, at the least, that comes at great expense.)
Am I all wet? I just spilled my scotch all over myself, so, yes, I am, but am I intellectually as well as literally?
