Anyone tried Ansar Supersound Audio Polypropylene Caps?
I'm told polypropylene are best in the coupling position.
I've just ordered some to replace the coupling caps in my pre-amp. My preamp has "screw on" coupling caps so no soldering required (until I decide on the permanent ones).
Not much wrong with the Obligato Gold ones in there at the moment (in fact they might well be better than the Ansar's) but as they're cheap it'll be fun to try.
Any other recommendations welcome of course.
