Has anyone upgraded their preamp with V-caps?

Jppenn, I am reluctant to use > 1.0uf size V-Caps mainly due to cost. If cost was not an option I would use V-Caps exclusively.

Pauly, have you had a chance to try the relatively new Sonicap Platinum caps? They are a hybrid teflon cap and their cost is about half of the V-cap.

I just replaced .1uf REL/Audiocap TFT coupling caps in my Atma-Sphere MP-1 LS with V-Cap TFTF. With just a few hours break-in, it's surprising how much better the V-Caps are than the REL and how big a difference there can be between one teflon cap and another. Furthermore, this swap made a greater improvement than replacing oil/paper coupling caps in my amp that I know to be inferior to REL TFT-- confirming perhaps the critical importance of the preamp in the system.

I can't speak about the teflon v-cap in output stage application but would like to comment that replacing 2 x 3,3uF Mundorf silver/gold recently in my Omega DUOs tweeter XO made a huge improvement. Very costly upgrade but worth every penny imo.

Sherod, I have not heard Sonicaps. A couple of folks have recommended I try them.
