One of the great misconceptions about AC power is the difference between passive and active devices feeding your equipment.
Manufacturers of passive AC devices like conditioners, low-Z suppliers of "added current", and isolation transformers all share one thing in common. They cannot add anything meaningful to the AC power. They can only remove unwanted artifacts. Which means they cannot do the critical work of regulating or repairing the AC power feeding your system.
One might wonder why we want to regulate the power and the answer's deceptively simple. Your connected equipment's performance depends on a perfectly steady supply of full sine waves. Anything missing from the sine wave or fluctuations in the voltage caused by the very equipment being powered results in worse sound.
A passive conditioner is kind of like adding lower resistance tires to your car in the hopes of better performance. Yes, your mileage might increase but those tires won't help you up a hill. The only way to get guaranteed performance is a more powerful engine.
And the only way to get a more powerful engine is to actually have an engine powering your system—exactly the function of a regenerator.
Lots of disinformation out there but the one thing you can hang your hat on is this. If the AC power isn't being produced by an active power amplifier, you're not adding much needed energy back into the power and thus unable to regulate the AC.
No matter how ingenious, efficient, and lightweight a bicycle might be, it'll never compete with a motorcycle.
