AC regenerator

I guess I'm the only one who has not had an enthusiastic experience with AC regenerators. I've found restricted dynamics with it in my system despite reviews stating otherwise. However, it did clean up the sound.

What devices do users connect to isolation transformers, or filters, or regenerators? For example, with regeneration: digital, turntables, preamps, but not amps because of dynamics loss?

Power conditioning is in my to-do list. So far I only have 2 dedicated lines into 2 aluminum boxes housing good outlets and then good power cords.

Thanks!

^^^I run PS Audio Power Plant Premier power regenerators in my system. 1 for each monoblock amp and another, the P5 newer version for my other components. The PPP puts out 900 watts continuous. Each power amp consumes 300 watts continuous at full class A bias. There is absolutely no loss of dynamics/performance.

Currenly have both PS audio P10 and Purepower 2000 +additional battery pack. Both are better than wall AC for most of my electronics except power amps. I have 4% THD from the wall (dedicated subpanel).

Some electronics are better on one over the other.

Best sound is thru Purepower disconnected from the wall running purely off the battery. (0.8% THD). WIth the additional battery pack, I can last 90min just running the preamp and the phono. However, after 45mins or so, music loses dynamics. I suspect as the battery capacity is dminished, the output imped goes up and reduace current delivery. Each regen., has its own issues so different results with different electronics are expected. They will react differently to different artifacts.

Recently tried a bunch: isolation transformers, PPP, RSA adimitri, shunyata talos.
