Power Cord Shielding

There has been tons of discussions regarding power cords. For me, shielding is the most important factor.
Thus preventing AC noise emitting from the power cable which may interfere with the signals of other cabling in your system.

I have had some fairly expensive cables from the likes of Black Sand and Cullen, that when I ran a handheld AC voltage detector along its length, whilst plugged in, the line detector would light up. As for cables like Pangea and even some stock, manufacturer’s cables (Coda, Wyred 4 Sound) I get no readings from the voltage detector.

That said, I’m surprised to see how many amps have the IEC connection on the far right or for left on their units, right beside the speaker binding posts. I think in the middle of the amp, as far away from any connections would be best. Such as the Luxman 505uXII or the Coda CSiB.

What are our thoughts?

By far the best power cords I have heard are Moneoone Supernova. Zero shielding. You can see the conductors through the mesh. So much for that theory.

This is done to keep the powerful AC fields as far as possible from the sensitive pre-amp stage. Once the signal is amplified to speaker level it is proportionally much less important that these be kept separate.   

It all makes perfect sense once you understand what is going on.

If the amps are MB that will help, ay?

Routing is a very inexpensive way to reduce noise. Shielding is the number one way to dummy down sound. I like weaves for noise reduction and as little shielding as I can get away with.

Even TT RCAs that I use have very little shielding. 

All the systems I put together are black as night. ZERO floor noise..

Routing and weaves... I have one noisy box (cable PS). I fixed it..
