New speaker suggestion

Hello, I am looking at upgrading my speakers and want to spend about $10-12k new or used. While the speakers I have now sound real nice, I want more detail and wider soundstage, all that fun stuff. My system is as follows:

Paradigm 95F speakers
REL S5 sub
PASS X150.8 amp
PASS XP 17 preamp 
PASS XP12 phono preamp
VPI Classic 3 Signature turntable
Hana ML cartridge 
Aurender N100SC streamer 
Chord Cutest DAC 
Shunyata Denali 6000 v2 conditioner 
Nordost Heimdall2 for all power and interconnects. 
Thank you for your time and suggestions
