Well I’m not familiar enough enough with the IC speakers you currently have but I do own c34e’s and IME they’re excellent. The main thing to consider is how wide the dispersion is. I personally believe that speakers sound/perform better when they’re more or less pointed at the LP. So depending on your ceiling height and actual placement angles, you may not benefit. I doubt anyone will have the experience with both speakers to give advice directly. Again, my experience with the RSL’s has been great. Afraid I can’t say whether or not you’d benefit from switching.
