Best $10-15K bookshelf speaker?

The B&W 805 D4 Signature are spooky good speakers that bring out the midrange much more than the non signature version.

if possible give a listen to the Manger Z-1

unlike any speaker discussed on this thread, in a good way 

Joseph Audio Pulsar is a wonderful speaker, and it fits your budget.

Mine are strictly used for Rock &Roll, with an SVS SB3000 sub, to compliment them. (13x14 room)  Fritz Carbon 7SE Mk 2  Love them, Robert TN     Ps 1/4 the price $   Audition  them, you'll find them to be a keeper, pleasant surprise.

We sell kef, Focal Jern and Alta 

you may want to look at the new Jern 35 which is a tiny, ultra dense loudspeaker utilizing Scanspeaks best drivers.

the cabinets are constructed from graphite and cast iron and there is absolutely zero cabinet resonance

they sound more like a 25k to 30kpair of reference loudspeakers and when used with a great matching subwoofer you will find them hard to beat at double to triple the price

the Alta audio Alec and Adam floor standers are very small so they might work as well.

the kef reference ones are extraordinary and for 9k represent a great value for a reference loudspeaker.

the sopra ones are outstanding if you value resolution and sound staging.
