I have a AC Regenerator. Get dedicated line too?

It regenerates the power, not makes it perfect. The better it starts the better it will be at the end. The companies which make the regenerators or conditioners suggest you use good cables; they should know.

Again, from the PS Audio website:

"The PS Audio’s Power Plant AC regenerator takes the power you’re given from the utility, converts it to DC and then regenerates brand new and perfect power once again. For more than 13 years the Power Plants have been producing perfect AC all over the world, helping audio- and video-philes and people who simply want better results from their investment achieve the best their equipment can provide."

If the PerfectWave Power Plan is advertised to produce "perfect" power then it must be assumed that when you purchase one you don't need to upgrade the power cord to get perfect power.

To recommend an upgraded power cable would be hypocritical given their marketing.

I tend to agree with Mceljo. The PurePower AC regenerator takes any crap coming out of the wall, converts it to DC, which completely eliminates the grunge and then converts it again to CREATE brand new perfect sign wave 120V power which it stores in a bank of internal batteries and feeds the components this juice as needed.

The idea that the most important cable is from the wall to the power center was referring to a CONDITIONER, not a regenerator... totally different animal.

That said, I'm still very interested in hearing from anyone who has A/B'd this question with a regenerator. I'm not opposed to getting a dedicated line if there is something I'm missing here.

Stanwal, the tests PurePower has done on the juice coming out of the regenerator seems to suggest that it is actually "perfect" power... and considering the enormous difference it made in my system, it is believable.

Now as an aside, upgrading the power cord from the regenerator to my tube preamp made another enormous difference which I don't quite understand... anyone have any thoughts on why?

Assuming that the regenerator is producing perfect power the losses then start from that point through your system. It makes sense that if the new power cord does a better job of transferring the power to the preamp then you could hear a difference. All cables have some negative effect on the signal going through it since nothing is a perfect conductor.

Sure the Powercord from the wall makes a difference be it small or huge, it makes a difference! Age old rule Ladies and Gentlemen " Good sound in Good sound out" and yes that applies to powercords as well.
