Panasonic PX "Pureism" Capacitors

[Einric]

Just wondering........
Does anybody have any personal impressions of these Panny PX "Pureism" capacitors?
I have a pile of these that have been salvaged and still measure properly.

I also have some Panasonic Audio PSU Caps and Master TA-KEH II ver 3.0 PSU caps.
Any thoughts about these?

Does anybody have datasheets for them?

Thanks,
Rich

Here are a couple photos.
The PX caps are printed Pureism on one side.
The Master Caps are really interesting too.

It's customized standard capacitor, you should ask panasonic 😉

How is a 2004 US patent related to more ancient Pureism or TA Keh ?

I use these around processors on the analog pins, sound pretty good to me.
They are like a silmic but with a better midrange.
That patent was interesting, didn't say what the intent was from what I could tell.

This is very interesting but are the Pureism and Master caps still obtainable?

Probably only on the second hand market.
Plus maybe since they arent popular they would be less likely to be counterfeit.
