Twisted or Straight?

Thanks all. I'll go with the 27 vestal virgins approach. In lieu of that, the twisted 10 gauge in conduit seems like a plan. Not too expensive and likely to gain good results. Thanks again.

P.S. Per suggestions in earlier posts and above, I will be using the "star" pattern in that all grounds will first go directly to a separate ground rod (next to the one for the house) and then be tied together at the box to avoid ground loop noise. A preferred ground "star" approach. Thanks.

Marakanetz - The di/dt currents in the power cord are what matters. IF it is too inductive, the drops can be in the Volts, not mVolts. I have one of the lowest inductance cords on the market and it is getting rave reviews when used with power amps. If you read my description on my poer-cord page, it describes how the voltage drops can occur. Poor power cords can have the same effect that plugging into multiple power strips has, except on transients. If your amplifier has switching supply, the impact of a low-inductance power cord may be much less, because of the regulation.

BTW - twisting the two current-carrying wires has the additional benefit of radiating a smaller magnetic field that can impinge on nearby interconnects compared to two parallel wires.

Your delight is appreciated, Audioengr. Thanks!

Thanks Will, I completly forgot about the Virgins :^)

Just as long as your having fun and not burning down the house it really doesn't matter what you do IMO.

I ran six dedicated circuits to start and am now kicking myself I didn't run ten. There's just something about isolating every component, sub woofer and powered woofer section that really turns me on, and this time I'm being serious

The noise floor dropped dramatically with three circuits to two seperate systems. I can't help but wonder how much lower it can go.

This thread just keeps on getting better & better. Wow; 6 to 10 times the work that I had to do for my single dedicated line; is it really 6 to 10 times quieter? Could certainly be, but I really don't think I want to get that involved in this scenario. Have at it; whatever floats your boat is fine with me too.
Oz: I didn't mention above (I'm just not THAT into it) that some have found wire directionality to be a sonic issue, just as in audio cabling. That why I suggest aligning the printing on the insulation with all wires running the same way. I didn't try this myself, but some have temp'd in the wiring, listened for a day, then turned the whole thing around in the opposite direction & listened again. Hard to believe I know, but the results were that one direction sounded better than the other direction. By the time I had read about this, my own ded. line was already weeks old so I figured it was pretty much broken in & would only sound worse if turned around so I didn't bother with that test. Of course YMMV.
