Capacitor question

Chad,
Thanks for your input, it`s always informative and appreciated.
I did decide to order the Duelund CAST for my speakers(only need 1 pair). I hope my results match yours.
Regards,

Your Vcaps still need to settle in. Yes, CAST caps are more organic and musical without sacrificing any detail. However those Vcaps are nice and need some 400 hours......

You mean you've changed PIO coupling caps? Why did you make this decision? I've always considered stock BAT equipment perfect and no need to upgrade unless it comes to the point of repair. As far as I know Jensen PIO are great coupling caps and good sounding...
Did you chat with VK? 500 hours of break-in? It may take half-year while other circuit elements getting older... Technically does not make sense except for toy purposes seriously.

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/ )
