I’m gob smacked. What were you’re aha moments?

Ok thanks for these guide...I will experiment with that for sure...

One thing to keep in mind. This colored magnet thing is really an illustration of the power of COLOR with respect to sound quality, not so much the power of MAGNETISM since the colored discs are actually very low magnetism. It doesn’t help to use more powerful magnets. The Rainbow MagnaBlock from PWB is also only very slightly magnetic.

And I don’t wish to complicate this too much, gentle readers, or frighten away any newbies, but I should add this whole colored magnet thing is an excellent example of how some things that are not (rpt not) in the signal path by any stretch of the imagination affect the sound. E.g., colored magnets on bookshelves, glass windows, computers, iPads, books, etc.

I've tried the thickest, heaviest magnetic kitchen mats and they do zilch, nothing, nada to the sound or picture.  Go ahead and experiment as I did.  It cost me bupkis to try a half dozen.  One E-Mat on the main power panel-wow!  Try it, I recommend it (instead of TC at half the price) as it is refundable/returnable.  

Gee, you say magnets do zilch. But you should have heard something. Magnets hurt the sound. Magnets and electromagnetic waves clash. That’s why you get better sound by wrapping mu metal around large transformers. It absorbs the magnetic field. It’s also why removing the big ferrous door of the breaker box panel improves the sound. No angry emails please, I’m not advocating removing the panel door permanently, it’s just an example.
