Hm. I didn't know these REL caps. Now I understand to be REL RT polystyrene and tin foil and really good (according to 1 yest I finally found). So, maybe, maybe not it will be an upgrade. But certainly very determining for the whole sound of the amp.
Personally I don't fret to much over tube matching. I have never heard anything strange with just popping 2 of the same tubes in. Maybe I don't know what to listen for or I've always been lucky to have used close matches. Maybe I'm totally wrong.
There are some really nice PSVane tubes now too. Reverse engineered from old types and new types that are newly developed with new techniques. I haven't kept up with all the tests but new production has gotten a lot of new impetus over the last decade.
