That’s a double-conversion UPS: AC to DC, a small siphon for batteries and control hardware, and then DC to AC out.
I imagine an audiophile would say that the sine wave generated by such a setup wouldn’t be smooth enough. They’d want something like a double-rotary converter, so that a spinning generator is making the final sine wave.
- kazinator 8y agoI think pros in the music and sound reinforcement industry tend to be satisfied with rack-mounted power conditioners.
- ianhowson 8y agoBut the amp converts that AC back to a flat DC anyway! In any case, PSRR (https://en.wikipedia.org/wiki/Power_supply_rejection_ratio https://en.wikipedia.org/wiki/Power_supply_rejection_ratio) is a real, measurable thing.
- sjwright 8y agoSuch audiophiles don't believe in real, measurable things. And they certainly don't understand how power supplies really work.
