battery-based SS amps

right or wrong (i do not know which as yet), i'm increasingly of the mind that part of the typical flaws assoc w/ SS amps (midrange glare, aggressive treble, discontinuousness) relative to tube gear is a function of their power supplies coupling noise from the incoming AC to the output devices. torroids remove a lot of noise, but they also couple it, and amplifiers amplify everything.

(i'm not sure if tube based power supplies act like torroids do in this regard, or if the tube gain stages have a natural roll-off for AC-related spuriae)

point being, i'm wondering if SS amps w/ battery based power at various stages (input, driver, output) can overcome typical SS weakness and give tube-like sound without the tube.

insofar as products i know of, rowland 8/9 TI, ASR emitter, but thats about it. anyone know of add'l products? and can anyone speak to experience on this matter?

Not sure batteries has anything to do with it. A well designed noise immune power supply can come in both battery and linear, and yes, even switching flavors.

As for tube like sound well that's a different discussion altogether. To me it's in the overall design, not just the power supply.

As Jax2 mentions, RWA designs some very good equipment that uses battery power. Well worth hearing.
