Simply noticed no mention of Manley Labs. I've owned and enjoyed several of their pieces, not this one. Not a headphone guy, but admire their approach and versatility of concept.

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.
