I have a AC Regenerator. Get dedicated line too?

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.

Mceljo: That makes sense, my old cable must have been introducing some EMF grunge that did not come from the regenerator, but maybe picked up via air or proximity to other stock cables that are not shielded well.

Aside from shielding from EMF and EMI, I wonder if the upgraded cable's increased ability to transfer AC current also plays a factor? Either way, I'm upgrading all my power cords from the regenerator to components.

I have yet to be convinced that money spent on a dedicated AC line will pay off in sound quality.

The only convincing one should need is to consider the difference better shielded cables have made. The dedicated line is a no brainier ( 20 amp 10 or 12 awg), as it further isolates your gear from the rest of the house and gets everything (power related) off to the best start possible. I like to look at it this way if it's in my ability to effect the outcome of what I hear, I do my best to achieve maximum results from my gear, you can't choose the power cable running to your house, but once it hits the breaker it's all yours!

Hey Jdub39, you're killing me here... As an audiophile, I will do almost anything for better sound, and your reasoning is very much like my own... I want to believe, however, I'm trying to do what I always do, which is to "prove" to myself (and my wife, who lucky for me has very good ears) that what I'm spending money on is an audible improvement.

I can get dealers to let me audition cables with a money back guarantee... but have not found any electrician willing to let me audition his installment of a dedicated line in my home. Hence, the purpose of this posting.

Somewhere in A'gon-land there must be someone who has run a Blind A/B on this question.
