Speaker upgrade

I am planning on upgrading my speakers. I have the following equipment:

B & W 802N speakers
Jeff Rowland M301 amps
Jeff Rowland Synergi IIi preamp
Wadia 270 SE tansport
Harmonix 777 DAC
Audio Magic Power conditioners

I listen to mostly female and male voaclists and older jazz. I am currently happy with the sound that I am getting but I have extra funds at this time and want to upgrade my speakers. My budget is around $10,000. I will sell the speakers after I sell the new ones and use that money to buy the Jeff Rowland 302 amp. What is out there that is a must audition speaker for a 15' x 30' listening sapce? Thanks again for any suggestions.
