yes, but a power supply will only give so much....more related to the lack of an OT imo....Gm is Gm regardless of the construction of the active devices...
Right. The PSU has to be capable of the extra power. But many tube amps have that; the better mfrs just rate power at low (very low for stereo/hi-fi) THD. Then there were the sleazeballs who came up with alternative terms just so they could make outrageous claims...
What's the world coming to? Probably play a 53 year old bass as well.
