Thanks Ian.Interested to learn of unplanned decommissioning issues with OS-CONs. So far I've been lucky. My main audio implementation is in a Stage 2 VSE Allen Wright output conversion of original SONY XB-940 SACD player, assessed before and after. The sonic improvement was startling over the originals (Nichicons?). I was pleasantly flabbergasted. A learned audio designer friend of mine swears by them. I guess one major limitation is higher voltage ratings are not offered.
Limited experience with BGs. Others suggest longish running-in period, warm and open sonics, and perhaps not the last word in PRaT and frequency extension?

I use the United Chemi-Con solid polymers (similar to OSCONs) a lot in power supply use. They are not so great as audio coupling caps though. They are particularly great in digital circuits. I use them all over the place in my DACs.The low voltage is a definate problem, the wired ones go to 10V and the SMD to 16. Even with the 16 I've fried several.
Thanks JohnMy (albeit limited) understanding of OS-CON chemistry is that Sanyo utilize an "organic salt". Maybe also a "solid polymer"? Whatever its DNA, agreed, OS-CONs and their ilk contribute positively to DC quality in digital circuits! I've ordered more OS-CONs, Panasonic FC and BG PK for my current phono stage project and will roll 'em over the next couple of months. Thanks for helpful contributions everyone!

an active crossover? The PCB size dictates that I stay with electrolytics for coupling caps on the outputs from the op amps. Stock they are standard polarized 100uf/25vdc. Should I go with bi-polar caps???
