Rollo,
Glad to hear this worked out well in your application, and yes, V-caps (either flavor) are wonderful (I've used both) but may not always be the right fit for best overall synergy of any given system.
Sonicap Platinums are also wonderful, a little less expensive and have a little more air on the top end, where V-caps tend to have slightly sweeter mids -- and I emphasize *slightly* as both caps are truly excellent. Then there's the new cap in town -- the MWI MOIP caps (and maybe teflons too?) and these appear to be getting a serious look from some experienced people.
Also, I don't think that a teflon cap is always the best choice -- it all gets back to synergy and what type of voicing you are looking for. I can imagine for example, that a teflon cap in certain vintage pieces would totaly change the voicing to something that may not be compatible with the other components or the signature sound of the original.
I also probably wouldn't use a cable burn-in device for caps -- it's not a realistic, real-world music signal, is most likely not at the correct level, depending on where the cap is used, and just seems like a bad idea to me. I think if this were to be a beneficial way of breaking in these caps the manufacturers would be building large break-in devices and running the caps in before selling them, because who wants to sit around for 600 - 1000 hours for them to fully form?
Sorry, but no matter how good a part, piece of gear, etc., blanket "this is the best" recommendations always leave me a little skeptical.
