Power cord that improve the soundstage the most?

Herman,

There aren't any $3500 upgrades left to do. I did them all before I even thought about this kind of tweak. That goes for all my cabling - you should get good wiring as you develop your system, but IMO the only time you should even think about splashing out for megabuck wire is if the rest of the system (including the room and the power delivery to the wall) is right where you want it.

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?
