Capacitor question


I have BAT VK-150se amps powering SF Amati Homage speakers. I replaced the stock BAT/Jensen POI caps with CuTF V-Caps. There is a lot more detail now, however, the sound is thinner, brighter and fatig

Yeh, some caps take that long to sound their best. Them are the facts and listening over time has proven it out. One can certainly do better then Jensen PIO caps, but one has to suffer the burn in time with Vcaps.
@David- Teflon has one of the lowest Dielectric Absorption rates, which makes it one of the best dielectrics out there(next to air and vacuum). It also takes the longest to burn-in(worth it though). This little item removes a lot of the pain: ( http://phonoclone.com/diy-rack.html ) Should you decide to build one: Note the last sentence of the instructions, as your caps are non-polarized. Hopefully, when you installed the caps, you were aware of the orientation recommended for most of the better film caps: ( http://www.v-cap.com/installation-notes.php ) ( http://jimmyauw.com/2010/04/24/observing-inner-and-outer-foil-of-some-popular-capacitors/ )
David, I ran pink noise from my tuner for 2 weeks 24/7 with the tube bias turned way down and a fan on the amp. Then a day of break.in disc.I believe the reference recording version. Then a listen confirmed that break in was complete and worth the time. The caps should be very organic. If not, its not the caps. I have many friends using the VCap cutf and none have bright issues or clinical sound. patience---Jallen
You may want to parallel the vcap with POI to get the mixture of sound. Play with the values.
Its not a good idea to parallel coupling caps. Different caps have different 'speeds' on account of their dielectric constants. The result smears the sound- that seems the best way to describe it.

You are always better off just giving it your best shot with the best cap you can afford. V-Caps are some of the best out there. Do give them some time to settle down.
