Importance of Power cords feeding Conditioners

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

My question, if this is true and it seems so to my ears at the demo, that it is, is it equally true for all power conditioners? In particular, I am using a Pure Power APS 1050 regenerator.....

it seems that it is just as important for AC regenerators as well. The reason is that AC regenerators regenerate the output AC sine wave using electronics (called a power inverter) that runs off DC power that was created using the AC from the mains/wall outlet. Without bogging you down in too many details, inside the AC regenerator there is a sine-wave generator that runs off DC (created from the AC from the wall outlet) & this sine wave is fed into a power amplifier that amplifies the voltage to 120VAC & also provides the capability to supply several Amperes of current (that your CDP, DAC, TT, preamp, power amp, etc, etc can use). This power amp is also running off DC (created from the AC from the wall outlet). So, if you end up using an el-cheapo AC power cord & you have distorted AC going into your AC regenerator, then, the electronics inside will run off a corrupted DC power supply which will show up as less than the best sonics possible. So, use a better/best power cord within your budget.
