Well, I think it's a question of how much battery is enough for the application, rather than AC vs. DC, per se. I can say again that my own (home use) DAC is much better from a battery. Perhaps this has partly to do with its "PS design", which is a wall wart, and no doubt the device's low power requirements factor. Although it runs Class A, 5 hours run time on a motorcycle class battery don't drop the battery voltage significantly. I remember some big-ass battery packs used for on-site recording installations. However, some of those old mics and tape recorders were phenomenal, as good as any that plug in to the wall.
It is funny to reflect that I once thought the PS300 would solve my front end electricity problems. Now and then I ponder the idea of battery powered amps. I think a couple of them have been offered "comercially", but I am not familiar with any, and I wonder what (if anything...) they would be good for, other than dodging AC line problems. Everything would probably have to be SS.
Best regards,
