Importance of Power cords feeding Conditioners

As promised, I checked a range of cords on my Pre Power APS 1050 regenerator. I picked up a Nordost Valhalla and Virtual Dynamics Master 3, quite cheaply, over the last couple of weeks;

First up, the generic, thick copper PC I have been using for years. Cost abot $30, no comment on it, used as baseline

Nordost Valhalla: A crisper, cleaner sound, more dynamic, a bit more detail heard on the recordings. I thought the soundstage lacked depth and the sound a bit clinical. So better, but not by much.

Lessloss DPFC Origonal: A bigger step up, the same improvement in dynamics and detail, but sounded more natural a better musical flow, definitely more enjoyable

VD Master mark 3; Very similar to the Lessloss, but with better base grip. More enjoyable for that.

So there clearly was a difference and the Lessloss and Virtual Dynamics were about equal in quality, though I preferred the VD. I would say there was not as much difference as putting the same cables on the amp or CD player, perhaps that is accounted for by the Pure Power being a regenarator, not a conditioner. If I had one, it might be interesting to repeat the comparison with a conditioner, but I don't have one.

So that's what I found.

I disagree that the PC to the conditioner is most important. The most significant I've found is PC to source. I have noticed differences w PCs to conditioner, true. But not nearly as dramatic as PC to source.

That seems to agree with what I found

Well, if your source is plugged into the PC then I would suggest that both power cords are important.

I'm not saying that the PC to the conditioner is not important; I'm saying IME it's not the MOST important.
