Speakers "To close to the side walls

Yes, dipole speakers (Audio Artistry, Mirage, etc.) are specifically designed to minimize side wall reflections.
Toe-in will help as will placing damping material (foam rubber, carpeting) on the "first reflection" area of your walls.

I have them slightly toed now. I have EAD PRE-Pro and Amp.
I wonder are the Paradigms the weak link here?
I am considering getting a new TV which can be mounted on
a rack, which will eliminate 2 sidew racks and save 44".

Thanks for the feedback

dipoles like Magnepans, electrostats, etc. they have a figure-8 radiation pattern and are very fogiving of side wall placement unlike conventional loudspeakers

More on my side walls. Will 15" from side walls make a
significant difference?

Assuming you are still talking about your Paradigm's, and assuming that you have them toed only slightly in, and assuming that you have not treated the 1st reflection points, yes it could make a substantial difference. HOWEVER, if you had your speakers set up properly before (but for the side wall closeness) your speakers will now be too close together and your stereo image will narrow substantially and the sound could become congested. If you've set them up correctly the first time then you will have to move your listening position much closer to the speakers (about 20 inches).
