LS50 vs R11/7/5 Meta

I have the LS50s (non meta) since it launched many years ago.  Since then, I've upgraded around the Ls50s -- Parasound Hint6, Mogami wire / interconnects, Technics TT.   For me, the only issue has been that the LS50s are too small for my room, but they're just too a good a platform that I really couldn't want for anything more.    The R series and LS60s have recently piqued my interest.  LS60s are not for me as they are powered and I want a separate amp.  So, I'm wondering if anyone has experience upgrading from the LS50s to something in the R line?
