Are there any problems with using Xicon capacitors in my tube amp?

[audio]

Does anyone know anything about these Xicon capacitors? Are they decent or junk? Due to space limitations in my tube amp, these are the only brand that will fit.

Not a friggin' clue. I try not to look inside stuff!

Anyone else?

The Bottlehead Paramours have come stock with XICON's in the power supply. I have no complaints. All the tweakers over in Audioasylum swear by Black Gate capacitors, but I have no firsthand experience with anything else but the XICON's in the PS.

I replaced a capacitor thats actually in the signal path at the output of my Foreplay preamp a few weeks back with an Auricap. Took about 3 weeks but I believe there's an improvement in transparency.
