My issue with this review and many other of his on ASR is it’s always about noise. That’s just one aspect of things. This unit is advertised to keep as close to perfect wave for power. Feed it some junk and see what comes out. Also burst some hard play passages. What happens. None of that. No listening comparisons. Just a crappy review.
PS Audio PowerPlant 12 Review (AC Regenerator)
This is interesting. The testing concludes that the filtering inside of the actual electronics device is what matters and that this PS Audio product actually adds its own noise. Some irony.
