Sorry Sherod for the confusion.
No I was just posting a link of a guy who owned a vintage amp (who loved it) with foil caps got it back from being overhauled (no doubt with poly) and it lost the magic. I too found the same with my speakers. It was much harder than I thought to replace the vintage foil caps and get something as good or better. That is where Duelund came in. It was only then did I find a cap better in all ways. I had mentioned when I heard all foil (for the first time) from amps to speakers one would have to deaf not to realise there is something real about the sound.
In the amp I only have used foil caps, Duelund and Jensen. I had heard the same story as the link I have posted (changing to poly caps) so many times I did not even do it.
As Frederik said even Steen stayed with vintage caps till his own went in. (VSF) In that other thread that Atmashere said
"Most older paper coupling caps while not very good performers were in fact very nice sounding and are actually sought after for some of their qualities".
The gist of that thread was (to me) while replacing caps you get better low end freq less noise but can lose the "magic". Magic is hard to measure as opposed to S/N of which poly would excel.
We need a magic meter! (just kidding) Something that could measure how accurate the instrument sounded.
