Once I got my PPP back and installed into my system, their was a noticeable difference is sound...The noise floor was so low that the music presented itself as completely new recordings. To hear the finer details in the sound was astounding.
I do not believe line conditioners would provide you with the same result as a power regenerator could based on how the 2 work, which is completely different with completely different outputs.
@keithjacksontucson if you can find a used P5 or P10 I'd buy it in a heart beat or even a PPP as it will support up to a continuous load of 1500W which a significant continuous load.
