Advise Needed, Best speakers for approx $15,000

Hi There,
Cary 306/200
Pass X0.2 Pre
Halo JC1 Monoblocks

Musical Tastes mainly pop, female vocals, old and new rock, some heavymetal , some dance.

Room is 30' long X 20' Wide. Listening distance is 10'

I have a budget of about $15,000.00 to play with. Looking for speakers that are dynamic,coherent and have good bass extension and slam along with all the other usualy hifi qualties, transparency, detail,openess and imaging.

So far have been seriously considering:

JM Labs Utopia Alto's
Vanderstenn 5A
Meadlark Blue Heron2

Other possible choices:

VMPS RM/X
Something from Kharma
Revel Studios or Salon's
B&W Sig 800's
Wilson WP7

I live in small city , I can audition none of these locally. Loooking for advise, opinions on the last speaker I will buy for a long time.

Thanks,
Magoo
