Excellent review of CAPACITORS Must read

I got some Mundorf silver/oil caps for my integrated amp and I just ordered some V-caps. I'm very anxious to hear the differences.

I received a favorable review of Mundorf Silver/Gold who compared them to V-Caps and preferred the Mundorfs as couplers. After chatting with Mundorf about the differences between Silver/Oil and Silver/Gold, I installed the Silver/Gold in the phono stage of my Atma-Sphere MP-1. These are fine coupling caps-- detailed, neutral, and extended, to my ears exhibiting no shortage of bass or dynamics as remarked upon in the 21 Cap review. Also the Silver/Gold may be preferred over the Silver/Oil in the hot climate of some tube amps (the Silver/Gold is rated to 85 degrees C as compared to 50 degrees C for the Silver/Oil.) In any case, there are lots of fine caps in this review, and while I'm as lunatic as the next 'goner I just couldn't justify the price of V-Caps.

Does anyone have experience with a V-cap OIMP( oil impregnated) as a preamp output cap and have you also tried bypassing that cap with a smaller V-cap teflon cap?

I have the OIMP's(4 ea)in my dac and was told by the designer to bypass with .01 TFTF's. Has anyone compared the TFTF to Jensen Four-pole to Mundorf's? I have six more caps to replace and was wondering what to choose.
Is it advisable to mix-n-match different brands of caps? I have Jensens' for the the PSU, OIMPS for tube output.

Wondering how the V-cap TFTF will perform in a XO tweeter circuit. Any experience anyone?
