Importance of Power cords feeding Conditioners

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.

Power cords on conditioners is indeed important , and matching that cord to your unit is of the utmost importance . I tried many power cords on my Shunyada V-Ray , all of similar girth , it was there rather pricy Anaconda that rang my bell .
We used to call it the humpty dumpty affect , if you don't get things right at the beginning , nothing you can do will put things back together .
