Built this up a few days ago, its a Kumisa III headphone amp which can also be used as a pre, classA, the op-amp is a servo so signal DC blocking caps are not needed, the input and output stage is discrete.
I'm now adding better regulation with improved PSRR.
It shouldn't be too hard finding a case for this one as its quite small
