Power cord that improve the soundstage the most?

From my personal experience over the last 2-3 years during which I've heard many different brands of expensive to ridiculously priced power cords is that my personal prefs tend toward Shunyata powersnakes all around. I owned Taipan, Python and Anaconda (non-Helix) cables with a Shunyata Hydra8 and Hydra4 for well over a year and was extremely happy with the results pushing power for my Esoteric sources, Edge amps, Classe SSP-600 pre-proc, Sony Direct View CRT and Lumagen processor.

I recently made a jump to an Esoteric P-03/D-03 combination along with an Edge NL 12.1 amp; during this same timeframe I also was A/B comparing the new Shunyata Helix line of Alpha and VX cables. I have found final state based upon all-Helix level Shunyata cables as they've managed to improve an already impressive line of powersnakes. My system has the following;

Anaconda Helix Alpha 20-amp (to power conditioner, most important cable in system)
Python Helix VX's (for all gear with digital circuit)
Python Helix Alpha's (for all amps and non-digital gear)
Python Helix Alpha for REL Britannia B1 sub

This combination kicks ass quite candidly and (to my ears) gives me the same performance as cables costing even more per meter.

The real surprise came when I changed my Hydra8 for a Furman IT Reference 20 active power conditioner; all I can say is that balanced, symmetrical power is the way to go. The entire system, even my CRT jumped drammatically from the beginning.

A dedicated high-throughput circuit for your system is also a prerequisite no matter what path you choose.

What power conditioner and equipment do you have?

Send me email if you want to chat further...I've spent alot of time in this area for my home.

Getting back to the original question, the JPS labs cables are great at increasing a soundstage, because they highlight the top end a bit more than others. They could be an issue if your system is on the brighter side though. The Shunyatas have very defined imaging, but won't give you any more perceived soundstage depth or width, because they're pretty 'thick' (but not necessarily slow) in the mids. Purist is great if you have a system that is very revealing up-top, and you'd like a more 'organic' sound.
Without knowing how your system sounds, that's about all I can add.

JPS Labs Aluminata. Once you try this pc in your system, you will understand. I got mine for half of retail here. Yes that still is a lot of $$$.

Tplavas,
What is the status of your own line of power cords?

Sherod,

I'm still talking to the beta-testers to try to get the clearest picture of what they're hearing, and then integrate those ideas into what I'm hearing. I specifically chose people that I know and trust, and who have systems that run the gamut of what's out there. So far the majority of them have found at least one model of our PC's that they've liked, and wanted to keep, which makes me very happy, as I really am trying to create PC's that don't sell the 'one size fits all' philosophy, although they will all share a 'house sound'.
Honestly, I'd really hoped to have my cables out there by now, but like the audiogeek that I am, I just can't help trying different permutations. And now we're approaching the worst time of year to introduce a new product. :(

If you'd like, I could send you a pre-production model in a few weeks, just to hear what you think. At this point, I'm already prepared for cheers or boos, since I know that it's impossible to make an audio product of any kind that will please everyone.
What PC's are you using now, and on what gear?
