PurePower APS power cord

Bombaywalla, looking at your Systems I don't see a Purepower listed. Do you have one and what power cord do you use?

correct I do not use the PurePower AC regen in my system - I use a PS Audio P300 AC regen. Different make/model but same philosophy re. AC signal regen. I use an ESP Essence Reference to my P300 Power Plant with very good results.

PurePower APS users, do you see any improvement using an aftermarket power cord to supply power to the PurePower unit? It's an AC regenerator, so I'm wondering if a nice cord upfront would make any difference....

oh sure it will! And, the reason is that, even tho' the PurePower is an AC regenerator, the regenerator itself needs electronics to create the new AC waveform. Basically, an AC regenerator is a power amplifier designed to output a 60Hz/programmable freq sinewave with a defined amount of current (3A, 6A, etc). Inside the AC regenerator there is an oscillator that generates the 60Hz/prog freq sine wave that goes thru the power amp to the AC outlets. All of this electronics uses DC power that is obtained from rectifying the AC coming from your wall outlet. Thus, the quality of the AC power matters a lot.
It comes to me as no surprise that others (like myself) have benefited from upgrading the AC power cord. I believe that you will too....

Same here...my experience is the same as Puremusic. For the longest time I held off on using anything but the good quality cord supplied with the Purepower unit thinking that with the regeneration+storage into batteries and SOTA cord could not possibly help. I was dead wrong. Improved macro and micro-dynamics; greater resolution and fullness; tighter and more powerful bass; even better sound stage and imaging; improved coherence and refinement; enhanced musicality and realism and energy.

Bigamp,

The Elrod Statement Gold power cord on my PurePower 2000 made a huge improvement over the stock cord: Improved macro and micro-dynamics; greater resolution and fullness; tighter and more powerful bass; better soundstage and imaging; improved coherence and refinement; enhanced musicality and enjoyment.

Your thread is an odd coincidence. I have the 1050 that I bought used a couple years ago. For most of that time I've used an after market cord on it; one of those big thick monsters. Decided I wanted to change things up. I had lost track of the stock cord power cord, so I emailed Purepower and they sent me a stock cord at no charge! I received it 3 days ago. (cudos to Purepower) Since installing the stock cord and taking out the after market cord, the speakers are playing with a renewed weightier sound. So, somehow the aftermarket power cord had a negative impact on the 1050 and my overall system performance. This is in my system of course. Your results could be different. Purepower used to recommend simply using the stock power cord. I don't know if that is still their stance or not. Other owners have sometimes reported positive differences by using after market pc's on their unit. You may have to go through trial and error comparing the stock power cord to a few after market cords and listen for a while to learn if you hear any differences. If you get the 2000, I would recommend allowing time for the stock power cord to play with the unit until you are sure the sound of your system is stable. This will establish a baseline for performance. Then if you choose, insert an after market power cord on the 2000, give it some time, and compare the sound before and after the after market power cord. Good luck.
