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

Refrence 3a de capo
Harbeth 7es
JMR super bliss
B&w pmi
spendor models
merlin tsms
slick2
I have the De Capos so I'm biased :) but i have used them with 3 different tube amps and they sounded great with all of them. 35 wpc PL2, 4 watt decware and 10 wpc Vista Audio I84.

they come up used btw 1000 and 1500 and sometimes higher.
I will go with Harbeth 1st Capo 2nd but Harbeth is $700 more expensive.

If I were you with $4000 , I will get Tannoy Stirling SE
How about KEF LS-50 with a REL sub, for low to moderate listening you may not find a better monitor. It will certainly compete with monitors you mentioned. At the very least give it a listen, it is unlike anything I have heard in years.
