Importance of Power cords feeding Conditioners

The Running Springs comes with (if opted for) a Mongoose Power cord which is modified Cardas Golden Reference power cable. Which I beleive indicates it must be important to start as close to the wal outlet as possible.
I've never tried replacing the Mongoose with a standard power cable but it may be worth a trial.

Power cords come with a variety of physical attributes, but the single most important "spec" for a power cord is its gauge (AWG = American Wire Gauge) The lower the AWG number, the thicker the conductor. The thicker the conductor (other things being equal) the better the energy transfer.

The two components that generally require the most/best energy transfer capability (AWG = 10 or larger) are amplifiers and high capacity power processors, like your APS. There is one (counter-intuitive) exception and that is DACs. Although their power requirements are low, for some reason, they seem to perform best with 12 AWG or larger PC's. And of course, anything containing digital data circuits (switching, converting, volume control and processing) should have a shielded power cord to help keep it from broadcasting digital RFI into the air. Hopefully the digital component itself has filters to keep it from inserting digital noise ("hash") back into the power line.

Yes, the power cord feeding the power conditioner is THE most important power cord for the entire system.

The best thing is that all your components plugged into the conditioner will benefit. So, consider spending 2-3x more on the conditioner cord than each component cord.

Not all PCs are designed for high current. So, what sounds great on a CD player may cause restricted dynamics and a collapse in soundstage if used to feed the conditioner.

In terms of thickness, there are pros and cons to a single thick strand vs. multiple thin strands. It would be too hard to generalize, as designs will vary in their success for each approach.

I have no experience with a power regenerator, which is an entirely different concept. But, do experiment.

From mains outlet to powerconditioner-- the powercord that links those two is extremely extremely important. use the highest quality pc you can afford.

Thanks for the replies. I have Lessloss, Sablon Audio and a Nordost Valhalla on it's way second hand. I will do some cable swapping
