I don't know much about "Wonder caps", but I do know stray inductance
when I smell it.  If your friend has to put his wonder caps in an
external box because they are so big, then it sounds to me like
he's just added more inductance in the external wiring than the old
capacitors had.  Also, how much leakage do ordinary capacitors have?
After all, audio systems typically have impedances that are rather low -
50kOhm in a phono preamp input, 8Ohms for speakers, for example -
not like some integrating circuits where you have to clean the flux
off the circuit boards to keep the stray leakage below the picoAmp level.
Reducing nonlinearities sounds important, but at first glance, it strikes
me that some of the other claims about these goodies aren't worth
worrying about.  Any coments?  (By the way, the remark "Yeah, but they
made the system sound better."  will not be taken as a useful response
to the questions I raised.  I would like to understand things in a little 
more detail than that.)
