I have encountered no problems related to the metal shield/can at all Lew. I've soldered ground leads to the shell and listened to the caps with the shells both grounded and not grounded. I can't hear any difference. I find no audible difference based on the orientation/outer foil location of the cap.

Most of these observations were done with the caps installed in a "McShaned" Citation II amp and in some other vintage gear.

So in the circuits I deal with I'm not bothered by the shell at all. And I am VERY pleased with the sonics. My friend and Grammy Award winning jazz bassist Phil Palombi has a Citation II amp I built for him that uses K40 coupling caps. The K40 shells are ungrounded BTW. He says it's the best amp he's ever heard - and he has incredible ears. My own opinion of the amp's sound is equally high.

That's my $0.02 worth anyway!
