I have a AC Regenerator. Get dedicated line too?

HifiHvn,

What were you referring to when you wrote that they misprinted the Pure Power owner's manual?

BTW, I bought my first audiophile gear at Hi Fi Haven, which was a high-end audio dealer in my college neighborhood in NJ. This was not a part of town you'd expect an audio store, on it's left was a strip club and on its right was Greasy Tony's Cheesesteaks, which was open all night and staffed with the shadiest motley crew imaginable. Ah, you gotta love college in NJ in 1980. Most of my friends frequented the two latter businesses, I think I was the only one who added HiFi Haven as a point of interest.

Alonski, that would be in reference to the comment made stating they regenerate the power, not make it perfect. And it appears that some believe a regenerators output would be influenced by its input. Also, an upgraded power cord should be used before the regenerator. If the product is designed right, it wouldn't have any influence on it. The information from Pure Power states "so there is no opportunity for outside influences to introduce unwanted waveform distortions." That alone tells me their product is doing the job right. If another manufacturer says something like a power cord should be used before it, it must have a design problem IMO. If it changes with just a power cord (small influence) before it, how is it supposed to keep the noise from the dirty power (major influence) from getting through, and giving you true new pure power? So one company's manual does not work for all in this case. I would believe the info provided by Pure Power. I would not go by what the other company says you need for their product. Pure Power should know how their product works also. They designed it.

A commonly stated rationale for upgraded power cords, which IMO is plausible, is the fact that the shielding they provide can prevent rfi (radio frequency interference) that may be generated by the power supply of an amplifier from escaping and coupling onto sensitive points elsewhere in the system, with unpredictable effects.

It should be kept in mind that a regenerator is essentially a power amplifier, having its own power supply, which amplifies the output of an internal 60Hz oscillator. Therefore that same rationale that applies to amplifier power cords would seem applicable to regenerator power cords.

It should be kept in mind, though, that any benefits from rfi containment will be unpredictable and highly system dependent. It should also be kept in mind that high quality shielding does not necessarily cost a great deal.

And of course this consideration implies nothing with respect to the desirability of a dedicated line for a regenerator.

In regards to the PPP, it is not a pure regenerator, but more of a power conditioner. The PPP, from what I understand, tracks the input voltage and makes adjustments to it as needed. There is no regeneration, just conditioning. So in this example, yes a power cord would make a difference.

In a true regenerator, such as the P-500 from PS Audio, the input voltage is converted to DC then back to AC. In this case, a power cord shouldn't make a difference. That being said, the P-500 operates like an amplifier and we generally upgrade amplifier cords with excellent results.

Dedicated lines! Of course they make a difference. Maybe the biggest difference when you look at sonic improvement for $$. If you have an open basement, it really is a no brainer. If you have to run new lines between the walls, that is a pain and can be costly.

But really, I've installed 24 homeruns in my listening room when it was built. I've yet to find a component that wasn't somewhat of a pig and loved having its own dedicated line. Some manufacturers, like Krell, in the first pages of the owner's manual, recommend this to be done before you even purchase a Krell amp and plug it in.

Over the years, I've heard many people are unhappy about the way the Krell amps sound in the high frequencies. I would bet that they have other components plugged into the same electrical line as their Krell amp. In my experience with Krells and other large amps, are like pigs and don't want to share from the same trough.

I'm now in the process of running a direct line to my computer server which stores all my music files and one to the cable and WiFi modems. And of course there is only one reason, to enhance the quality of the sound.

Oh, and as an owner of several power conditioners/regernerators, there is no doubt that supplying it with the best power cord one can find, will take they're performance up a notch or two. Of course, if you want to make more not so subtle mprovements, upgrade to better outlets, and change out the fuses for some of those new audio grade fuses that are causing such a stir. . .

I don't know the electrical reasons or explanations for these audible effects, and it seems strange that all of these tweaks make a difference but they do.
