Ken is wrong when he suggests that the PP should use thicker wire.
How do I know? Well because I've tried it. Thicker wire. Double runs. And I got the best performance with the wire I use, the copper version I should add.
Something in the mind seems to want to have big chunky power wires, but the truth is that they don't sound very good. Thicker wire has more inductance. Best to use the thinnest that handles the load, and the wire I use is rated 15-20A. If bigger was truly better, everyone would be using welding cable, and have you heard how bad that sounds?
I've been playing with some mains leads recently, and also I am finding the best performance with ones made from 14awg wire. And my amp is no low power thing. It idles at 500W+ so the mains lead has to pass, well a few amps!
The mains lead will be a DIY project. Pretty easy to make and works well, especially for the money (and especially if you use normal copper wire, means you can make a mains lead for a few dollars).
There is also another reason why I think that Ken is reporting the kinds of things that he is; PM or email me if you'd like to know more.

Beautox, I wonder what you mean that there is another reason for my posting?
I am merely reporting and sharing with others what I hear in my System. I have NO other reason. My name is ozzy on Audiogon and I have posted ther for many years. I am a tweaker and have tried so many glowing special products through those years. Some impress and work and some just don't.
My system consists of a Pass Labs X350.5 Amp. A Pass Preamp XP-20, Eggleston Works Andra 2 speakers and a pair of JL Audio F-113 subs. I have HiDiamond P4 power cords and 3 dedicated lines. On my Digital I am using PS Audio P10.
As I stated about my experience with the Power Purifier +++ there is more upper air that is nice, but the bass sounds truncated.
I would like to try the Power Purifier +++ running parallel with the electricity flow inside my Amp, but I don't think the Pass Amp has a direct path to the incoming IEC.
I will continue to update...
Well, even though the Power Purifier Double Plus PP++ didn't make it into my Audio system.
I must say with my Video equipment it has shined. I think its because of the lower power requirements.
The Video has a very nice deep blackness enhancements. However, it took several hours before the improvements reached the maximum. So, plug in/and play was not a good trial. You need to wait for the improvement.
So, it looks like at least at this point I will keep it for that purpose.
How long did you leave it in your audio system?
I find that in my system it takes several hours to really shine and initial impressions were more often than not, negative. In fact, its almost as if it sounds very bad, then you know it will improve with time.
May I recommend that you try it again it your audio system. I find that once it sort of breaks int, the change seems to be more "permanent" althpught there will be a breakin period when changing over, but significantly shorter ( depends on the current demands of the various components). If I go from smaller demand components to larger current demand ones, the break in periods is longer. When going the reverse direction, the break in time is much shorter.
of course YMMV
I had it in my Audio System for several days.
Strange thing to say. I wonder what he means, too. Is it a new marketing ploy?
