Really? How did you measure the Silver Rainbow Foil? The Green Pen? Demagnetizer? Just curious.
You are not just curious, you want to disprove everything I say here. I'll respond anyway:
I have the same disk here with and without treatments, including most of these tweaks, but even more important, I have the same disk with the rubberized coating and without. The one that makes the biggest difference. I can easily hear the difference and measure the difference.
