Ron Gurney installed eight CuTF series V-Caps into his own BAT VK150SE monobloc amps. Shortly after installation, Ron made these comments via e-mail (published with Ron's permission):

"Huge changes from the first listen. Upon initial power-up, the sound was muddy, distant, with a boomy bass. I thought I had done something wrong - cold solder connections; not all 4 tubes were working properly in each BAT 150SE, etc... I had expected the instant improvement that I heard with the TFTF caps. After only a few more hours, the sound changed dramatically. The soundstage became huge, a multitude of details emerged that I hadn't heard before, and the sound was crystal clear.

I am up to about 25 hours so far. I know that is very early in the break-in process but so far, I think I can already hear what you said about the "soul" of music. Already better than the TFTF's. Wow, can't wait for the full break-in. Correct me if I am wrong. Am I hearing in the CuTF caps, a similar sound as one would find in the wiring of copper interconnects, cartridges, etc. as compared to silver? More soul, more analog, more tube-like, more warmth, less digital, less coldness, less ARC whiteness? I made no other changes to my BAT mono amps, only switched the coupling caps from TFTFs to CuTFs. Definitely worth the price difference over the TFTF's, which are great themselves."
