Looking for some coupling caps for a rebuild project and in this particular case I want to use a copper foil PIO cap.  Looking at the PCX site I notice that most of the 630 volt copper caps come either in the standard casing, or optionally in a paper tube -- at about 3X the price.

Has anybody compared these and have anything good or bad to say about them in terms of sonics and reliability?

Thanks,

Jim

Hi Jim,
Stumbled over your old post.
I upgraded to the Jensen paper tube version from the standard alu house version in my Audio Note Meishu Phono SE amp, and the sound improved dramatically.
I find them to be more open, relaxed, detailed, and generally providing a "larger" soundstage.
Absolutely worth while the extra cost IMO.
They require a long brake-in of several hundred hours to fully open.
Greets,
Thomas

Thanks, Thomas,  Actually, I just got (only 2 days ago now) a matched pair of ampohm copper foil PIOs, but I still have aother project in mind where I might use the jensens.

Thanks again,

Jim
