How interesting. I can’t see it making any more than a minor difference.
Define minor?
Let's be honest, once you get beyond a certain level, and that level is actually fairly low, most differences in Hi-fi are minor, right? Yeah, we talk about huge differences but most sane people would struggle to see them as relevant.
Yes, I would say that removing the paint is a minor difference but it's a good difference and using the same criteria I would have to concede that the difference between a stripped and rewired RB300 and my RB3000 is probably minor too :0(
