Need to build a headphone system

I'm looking for advice.  I need a headphone system for an apartment.  I am  overwhelmed both by the variety of headphones and amps out there and the difficulty of auditioning them.  My budget is about 8.5K for amp and cans.  I listen to lots of chamber music, solo instrumental and other small group stuff, so I appreciate detail and responsiveness.  But I shy away from analytic - my main system amp has beautiful glowing tubes.  Although I stream a lot, I also listen to a lot of vinyl.  I wear oticon behind the ear hearing aids.  Music sounds noticeably darker and less detailed when I take them out.  So certainly not in-ear!  Any expertise on listening with aids is greatly appreciated.
