If you had to narrow your choices to 4 - 5 speakers

Would be helpful if you shared what speaker/sound characteristics you’re looking for, but here’s a list in order where I’d go.  I’m going over your limit — sorry I just can’t help myself.  It’s like a kid in a candy store-like thing. 
 

Joseph Audio
Alta Audio

Acora

Gershman (always a surprising standout to me)

Volti

Rockport

Vandersteen (if you haven’t heard them before I’d bump them up a couple spaces)

YG

Von Schweikert 

PMC

Perlisten

MBL 

Dutch & Dutch

I’d also recommend giving at least a look at the Treehaus speakers — they look very unique and natural (you’ll see what i mean) and also thought they sounded quite good.  Im jealous and wish I could go, but hope this helps and enjoy the show!!!

@bjesien I’ve never heard their monitor, only the Avant Garde and one of their older GAP models and they always surprise me by being some of the best sounds I hear at shows.  Most recently I heard the Avant Garde at the NYC show a few months ago, and once again they were in my top 3 for sound at the show, and there were some good speakers there.  Just my experience FWIW. 

@arafiq I recently read a post by someone (can’t remember who) who recently upgraded from the Perspectives to Pearls, and from what he said there were more similarities than differences and the biggest differences were that the Pearls could play louder and obviously go a bit deeper.  If I was you and in your room I’d be very torn between upgrading to Pearls or adding two good subs to your excellent Perspectives, which would probably greatly close the gap, maybe provide even better bass better integrated to your room, and be much less expensive.  Either way, it’s a high-quality problem.  FWIW. 

Here is a list of Axpona exhibitors fyi…

If Verity Audio is there they are a must hear. 

@willywonka Yeah I didn’t see it either but someone else mentioned them and thought maybe they know something I don’t.  Probably not though.
