New V-CAP CuTF capacitor

V-CAP has just released a new capacitor - CuTF - copper foil/teflon that they feel is the cat's meow. Apparently a lot of R&D went into it, per their website. It is more expensive than the TFTF but appears to promise the "soul of music" inherent in copper. I've been quite happy with the TFTF (tinfoil/teflon) caps I put in my BAT VK150SE amps but have decided to take the plunge with this new cap. Will post results in the near future.
