I have a AC Regenerator. Get dedicated line too?

Yes a dedicated line will help; a related question often comes up; why spend any money on a good AC cord to the regenerator when perfect AC will come out anyway? My experience is that using a very good cord to the regenerator makes it sound better; PS Audio says this also and Shunyata says the most important AC cord in the system is the one between the wall and the conditioner. By extension we can see that quality of the AC line must also have an effect.

If it is truly regenerating the power then I can't see a connection between the input and output. That's the whole point of regenerating the power in the first place, right?

If I upgraded the power cord, outlet, or got a dedicated line and could hear a difference, I would want my money back.

Here's a quote from the PS Audio website:

"The Power Plant concept acknowledges that we cannot control the quality of the home’s incoming AC power, nor can we fully repair its problems. Instead we simply ignore the problems, start over and generate new AC, thus eliminating the problem entirely. There is no connection between the input and the output of a Power Plant."

So it would be double-speak to suggest that an upgraded power cord would have any effect on the output when also claiming that there is no connenction between the input and output.

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.
