Speaker List narrowed down…

Here's what I can add....  The Estalon Aura uses a down firing woofer so it should play better closer to a wall behind it then a rear ported design.  I've heard the Estalon Forza at a friends house and they are special.  I'm sure the Aura will have some meaningful trickle down benefits from higher up in the line.

The Sopra No3 might be a great fit.  They are known to really shine when given space to work and you have the room for that to happen.  The Sopra's are front ported so while they do best with space to work, the space they need is more side to side and behind the listening position--they will work well closer to the front wall than most.  If you take a look at a pic of the Sopra's they have a large midrange driver that has a separate cabinet enclosure that doesn't get clouded from the bass drivers.  Good luck and cheers

You have some excellent speakers on your list! I went through a similar process/decision recently. Take your time, try to listen to as many on your list as possible and go with the pair that sings best to you. Putting reviews, opinions, specs and objective data aside, what sound will make you smile ear to ear when the music starts. You’ll have a few where you’ll try to justify they’re as good as your favorite. Cheers and enjoy the music! 

If you are near Philadelphia you can come over and hear the Perlisten any time.  Bring the music you enjoy.

Contact Bob Neill at Amherst Audio (MA) regarding the JMR's. He's a dealer and familiar with them. Could be helpful.

Since you have the Sopra 3 on your list which I wouldn’t really consider a narrow baffle I would highly recommend the Rockport Atria ii (used if you can find a pair) in your price range. Or stretch for a new pair. Amazing speakers and worth an audition. Good luck !
