Best monitor for under $4000.00

I have a dedicated listening room that is 13.5 X 18 X 8 high and is a well treated listening environment.I use Thor TA-1000 preamp with Thor TPA-30 mono blocks.They are 30 watt el-34 tube amps with understated power!I have had Kharma 2.2 before and though they sounded nice the room was overwhelmed with them!

I listen mostly to vocals,small jazz groups amd aucoustic music!I listen at low to moderate levels.I know I need to demo...but please point me in right direction.Speakers I am interested in are

JMR super bliss
B&w pmi
