Arthur, i've found that i prefer the sound of SS amps that use minimal to no output inductance. While this can make the amp somewhat unstable into some loads ( easily compensated for ), i think that it sounds so much more "liquid". Having ALL of the signal fed through a HUGE inductor can't help matters. The fact that most speakers are not one specific impedance across the band also compounds problems somewhat. While the "Autoformer" may keep power constant from tap to tap, it can't compensate for the various current draws that occur within each tap at various impedances. Td ( Time Delay ) of a circuit like that can't be very good either.
My opinion is that large transformers should be at the beginning of the power supply chain and no where else. That includes tube amps also, as the Atma Sphere OTL ( Output Transformer-Less ) are the best that i've heard ( so far ). Sean
