I bought a pair of RF-83s and a RC-64.
Nice, congratulations!! How do you like them compared to the 7's?
I found the 83s to be a little softer in the highs and maybe a little stronger in the mid-range. I had a week to A/B the 83s before deciding. The first night, they sounded awful. I thought they were defective. I let them play for a couple of days while I was at work in case they needed some break-in. They started sounding much better. They seemed to sound better each night. I went back and forth thinking that I had made my decision. Since they continued to grow on me, I decided to keep the 83s. They are both great speakers. Very similar, but a little different. It would be interesting to A/B them again since I haven't listened to the 7s for a while. Then again, that would probably confuse me again.
