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.

Thanks for all the suggestions.  I've listened to a number of headphones so far.  I have not been able to hear the RAAL's, so I guess I will contact them directly.  Focal's don't play well with my hearing aids.  Sennheisers do.  Audio46 was not much help.  Bus have been a low point in their stocking cycle, and they are not going to open boxes of hi-end cams just for a listen (which I understand).

@label19 - do you use behind-the-ear hearing aids for headphone listening? I have Oticon behind-the-ear ones for listening to my 2-channel system, but I've got in-ear hearing aids for headphone listening. Otherwise, the sound is not being directed at the hearing aids' mics....

I don’t understand.  What does this mean?  If brick n mortar stores are failing to meet your needs, the hell with them and just start buying ‘phones you’re interested in online with generous trial/return periods, whether it’s Amazon or direct from the manufacturers, and just do that.  That should be doable.  I’m sorry Audio46 was a fail.

@larsman I too have oticon behind-the-ear aids.  I see your point about in-ear aids.  That's going to be expensive.  My oticons are 6K.  What are you using for in-ear?  It might be worth the investment for me because the headphone system will be my main system in one of my two residences.  (My wife and I have been commuting for dogs years.)

@soix agreed.  That's what I'm going to do.  It's a little complicated since it's a headphone/amp pair I need.  I'm on the road a lot, so this is becoming a slow and frustrating process.
