I asked that because I do think it possible to get different results, but clean power is clean power and an abundance of clean power to draw-down (buffered/stored) in a transformer during dynamic passages is power you did not otherwise have on tap through the wall. So, what were the circumstances? Unless the answer is just opinion or hand waving, it’s an answer to be mentally plotted in a space of appropriate/inappropriate uses for power regenerators.
To date, no negative experience I have read of rises above "opinion", I’m looking for more than just "good", "bad", made my music "sound green"... I can’t process those in a meaningful way because I have come to fear opinions as completely subjective.
[Subjective isn’t bad, it’s just "thin" unless it comes with an abundance of descriptors such that the reader can relate to the opinion as a substantial one rather than someone at the end of a keyboard just being ...social and saying "it’s bad for music listening" ...the question remains: why? ...After all, it is just clean and abundant power. These discussions sometimes remind me of politics, a nasty topic that is light on fact, ignores fact, or builds on fact: the three are quite different. Sorry for bringing it up, but it is just an example.]
Given the wealth of technical material I have read on the topic over several years, and given the experiences I pointed to: How is it possible that the addition of an appropriately-sized power regenerator can generate a negative music listening experience? (I am open to any answer that informs, rather than a brush-back answer.)
