I can't think of any interesting opamps that work at +/- 12V that don't work at +/- 15V. There's a few +/-5V (ADA4897 comes to mind), but we rarely need to work in low power for audio. Some of the high analog output audio DACs would certainly benefit from a good +/- 5V line though (I might be mis-remembering the AKM449x series, though, might just need 0V and +5V).
I'm using one to power the
Soekris Engineering ApS, Products dam1021
This one would be happy with +-7-15V DC , so currently I do use the +/-15V. As the DAC consumes ca 800mA from positive rail I am stretching the limits the the SilentSwitcher here. So I would take one with +/-9V or +/-12V if you get some other requests for either. Would make life bit easier for the SS module.

pixelpusher - I do run two off of a Sony powerbank CP-S15.
One SS supplies the BPBP preamp (with MAYA and relay volume kit) and other SS supplies the Soekris DAC. Works fine... I just had to upgrade the power bank from some no name one as the prior was not able to supply enough current and shut itself down whe I connected both devices.

I second the need for +/-9V as that is what the CS3318 needs.
I would prefer an adjustable version as I would want to use the same Silentswitcher with different projects. I don't always know at time of purchase what circuitry it will be used with, it's just a very nice thing to have in the partbin.
Could you look into using LDOs where the output voltage can be adjusted by changing the feedback resistor?

Thanks Ergo, I just hadn't gotten around to post it. Can I use it, with proper attribution of course!
BTW the hole pattern seems OK but my CAD repeots the PCB size as 32 x 55 mm instead of your 56. Then again, what's a millimeter between friends ;-)
BTW I am looking at providing a version where you can change the outputs by replacing 4 size 1206 SMD resistors. Should be doable right?

Doable replacing 4 SMD resistors.
My SilentSwitcher measures 32.3 x 56 mm and is small enough!
Jan, most pcb cad programs has built-in to make drawings and then you will have exact dimension which are tied to the elements.

Sure, but give me a weekend and I'll tidy it up a bit and make all lines solid lines etc. I used my caliper and yes my boards are still 56mm too. PCB houses are very precise when doing traces but the cutouts are done with bit more reserve sometimes.
