I have the option to add either of these speakers to my current Yamaha RN-602 Nice used pair of RF-63's for $500 New pair of R-28F's for $600 Just for the sake of a higher end speaker and build quality, I'm leaning towards the RF-63's. Just have a hard time purchasing used audio gear. They appear to have been kept up very well though. Can't listen until Saturday. I typically listen to 70's and 80's rock on my turntable and some occasional CD's of various genres. Help....
