Replacement for Vandersteen 2ce


Hi everyone,
i have found this forum extremely helpful so I’m looking for some opinions on replacement speakers for my Older Vandersteen 2ce speakers. Been trying to do tweaks but wondering if I can improve the imaging and soundstage with something else maybe in the 2-4K region. 
Components are as listed:
Krell Digital Vanguard w/ Shunyata Delta NR PC
Acoustic Signature Triple X
SPL Phonos 
Marantz CD6006 w/ 
Digital from ITunes through RME DAC
Vandys have 15ft Taralabs RSC Primes which I was going to cut in half or replace but if I’m going to buy new speakers I’ll hold off.
I appreciate any help!

"Room is 16” wide x 14” deep snd have them 3 feet from back wall toed in slightly and tilted back a few degrees."

In my experience with the 2Ci model, the set up without any toe-in yielded much better results in terms of soundstage and imaging. Also, the use of sound anchor stands and how they're coupled/isolated to/from the floor, depending on the type of floor, made a big difference.
They also scale with the quality of the electronics feeding them.
@kalali okay I will square them off. Yes Sound Anchors with lead shot. Wood floors. 
No toe-in, no rack between the speakers, proper tilt-back per RV, listening seat at least 9'  from plane of speakers, acoustic treatment, acoustic treatment, acoustic treatment. Also try getting speakers closer to front wall, the rear-facing acoustic coupler works wonders that way. Bi-wire almost mandatory. They sound significantly better from mids up with bi-wire setup.
I own a pair of Vandersteen 5As and I had some issues with them.  I use a 100wpc stereo amp as I felt that I only technically needed to power the top half of the speaker since they already have powered sub-woofers in each speaker.  I was playing around this weekend and I hooked up a more powerful amp at 220wpc both of which I made so the only difference was the power technically.  As good as the smaller amp was, and it is outstanding, the larger amp was even better especially in more openness and easy of the music flow.  So before you make the change, speak with JohnnyR and see if yo can try another amp on them.
@bigkidz Since I started driving them with the Krell 200 watts per channel they sound much better. Yes I will speak to JohnnyR and see what he thinks. Maybe some new shorter cables will help. My old 15ft TaraLabs RSC Primes are probably hindering. I only need 6-8ft now.
