I have the 3.6's and had them for over 20 years. As I upgraded the front end over the years (from Adcom separates to the Levinson 20.6's and 23.5) the 3.6's sounded better and better.
Personally, I think that you will not find a speaker worthy of replacing the 3.6's with only 4 grand. The only speakers I've heard that I would consider replacing mine with is the Magico S5 as I was impressed with that speaker's ability to handle the low end of orchestral recordings.
It's unfortunate that the 3.6's are not taken seriously as they only cost about $4500 new (when one is willing to spend twice as much on a power cord).
I have a hunch you will be disappointed in getting rid of them.
