Power regeneration - good idea? PS audio?

And today through the snow falling I saw a monkey fly, upside down.

“An amplifier would have to be deficient, defective, or broken for this claim and  assertion to be accurate.”

Sagging voltage can reduce peak power output from an amplifier. I’ve also  encounterd distribution networks that are so stiff that they damage mechanical equipment.

A lot depends on the amplifier! In this case it was a tube amplifier. Tube amps have a filament circuit and when the voltage on the filaments decreases the transconductance of the power tubes falls off- combine that with reduced plate voltage and you can see substantial losses of power. But you will see a power loss with any amplifier!

It would seem the existence of large capacitors inside an amplifier would mitigate the impact of a voltage decline temporarily.

A Macintosh amp is loaded with capacitors so I don't see any problem with voltage changes

@jumia This is correct only if its for a second or two. If longer, a few minutes or hours then no. If the voltage is sagging it means there is more draw on the AC power- and voltage drops are occurring in substation power transformers and the transformer on the telephone pole outside your house. When this happens its guaranteed that the AC waveform will also be more distorted. Its this distortion that a good power conditioner is intended to correct.

Fluke Instruments is a well known test equipment manufacturer in the electronics industry. Here’s a short primer from them regarding this topic:

You can see that addition filter caps in an amplifier will have no bearing on this issue whatsoever.
