Paradigm Studio 40 v3 owner looking for 2 channel setup, Dynaudio Contour, ATC SCMs etc

It has been 10+ years with these speakers and they are great all rounders. I am looking for a dedicated 2 channel setup that is skewed towards music.

My room is 24 x 24 x 8 which is both a living room and listening room. The front left speaker cannot be more 3.5 feet from side wall and I cannot have both speakers more than 2.5 to 3 feet from back wall.  My listening distance is 10 feet to 12 feet.

Long story short I am looking for speakers that have good measurements and can go up-to 40 Hz in my room if not lower. And are good at lower volumes and I prefer them to perform well for long listening sessions. 

I love classic rock and good stuff from 80s, but listen to some recent music once in a while. Love to explore other music and some non western music!.

I looking for speakers that can throw a large soundstage in my room, accurately reproduce guitars/stringed instruments and human voices. Must perform well for those great 80s hits and older music.

I find MartinLogan quite engaging but they are not WAF friendly. I did hear B&W 805 series and did not quite like them, I think I may prefer older B&W CM series and I really liked Dynaudio Focus 220s and some what liked Vandersteen Model 3A when I heard them couple of years ago.

Here is the list I am considering(< $10K):

Dynaudio Contour 20 / 30
ATC SCM 19v2 / 40v2
Aerial Acoustics  5T / 6T
Harbeth Monitor 30.2 / Super HL5plus
Vandersteen Treo CT

I may or may not be able to audition Aerials and ATCs due lack of dealers in my area.

My plan is to get Preamp and Amp after getting the speakers. Sources will be lossless streaming and a record player.

I am looking for comments and suggestions from people who have listened to these speakers and have similar tastes and constraints.

thanks
