Power conditioning for computer audio

Hi Guys:

While snowed in today, I was surfing around the net and came across this AC regeneration product from PurePower. It looks like the product is used to clean up chaff from power utility lines. Can someone discuss whether and how so called Power Gremlins (see attached URL link) affect sound quality from stereo gear.

Does it matter if the gear is SS or tube?

What impact (if any) does a regulated power supply in a piece of equipment have on the quality of the unit's internal current?

BTW, the PurePower AC regenerators are not cheap!! See the attached URL.

Thanks Almarg. The second thread was right on point!

If power Gremlins are really finding their way into the final output that goes to a speaker, from a layman's point of view, that looks like pure distortion. I take your point about rf getting in the middle, but wouldn't that always be the case. It would seem that power-line Gremlins just crap up the signal even more?

I'm still looking for an answer from the forum, in layman's terms, as to whether it matter if the gear is SS or tube? And, what impact (if any) does a regulated power supply in a piece of equipment have on the quality of the unit's internal current? IOW, does an electronic power supply in a way also act like a power regenerator??
