Stan, I wasn't trying to bait you, but sometimes, I feel "we" get a bit too anal about things that either make no audible difference in practice, or make such a tiny difference as to not being worth bothering with.

I don't mean to instigate yet another ruck, but coupling caps seem to have come a very long way over the years, valve amps rely on them and my recent experiences of Muse fine gold and BP caps has been nothing less than positive, despite their low cost.

Oh alright, I'm missing the whole point - apologies all
