RE: Do russian teflon capacitors lack musicality?

Paper in oil and Teflons? Either can be some of the best. I think some
silver/micas are good.

Vintage? That's a lot more troublesome because capacitors have come a long, long way since even 2008.

Today's best caps are able to use a variety of technologies, and nearly
all of them if from really good manufacturers, are very much better than older stock of similar types-- in most cases.

Rel-Cap cu Teflons were always very good, and the old Sidereals were
another great performing exception. They were so good that they could be used in world-class equipment today!

Those are exceptions. If you've got an old "Mac" or a Marantz, Citation, Dynaco, or whatever, you should toss-out ALL of those capacitors-- some of today's "cheapies" will easily outperform them. Ditto for "Vitamin Q's"-- those things are really medium-grade by today's standards.

G.E., especially, made a series of round motor-run paper-in-oils.
These are excellent even today-- only the round ones have high performance.

It's to each his own with capacitors.
