If you like the sound of the R5's then you really oew to yourself to have a listen to the Rs3's and Rs5's as well. Depending on your room, the 3's may well be a better match. The side placed bass drivers give you a few more options for setting the speakers into to the room as well. I had the R3's (originals) for a while, and enjoyed listening to them. I only changed because I changed listening rooms, and the Spens I have now could drive the room better. If I ever have the money the spens could easily make way for for Rs7's. Rega have been making good sounding speakers for 20 odd years, and they do seem to learn all the time.
