I have a local unpopulated cap location near the + and - 12v supplies to NJM 2114 opamps (analogue out)
Panasonic left them unpopulated and I am thinking of adding a 0.1uf cap. I have a few in mind (not much room as I will need to lay flat under board 7.5mm clearance)
I have already fitted a 10uf tant here with good effect (increasing dynamics marginally) as the power is coming from a low noice LPS this is more about what might be worth adding in parallel
Thinking TDK 0.1uf ceramic X7R or WIMA MKP, possibly Kemet SMR
I can happily try all over time I have tried a WIMA MKS marginal too marginal to tell. I didn’t like a DME 0.082uf orange drop sounded a little lean and slightly edgier
Any recommendations or thoughts
This is about sound quality no problem to solve or any other reason than it might be better with another local bypass
I can see Panasonic did fit a ceramic on their Japan version but no details uncovered

The main thing you want there is low inductance, so a ceramic 0.1uF is fine.
So something like this ?https://uk.farnell.com/tdk/fa26x7r2e104knu00/cap-aec-q200-0-1uf-250v-mlcc-radial/dp/3772374
