Okay, after several hours of listening and breaking in. The sound has really opened up and the Quartets are clearly coming alive. I believe they are sonically better, by a margin mind you, than the RF-35's. Funny thing, when I turn on both during 2 channel playback, I really like the sound. They seem to have a little of what the other is missing, but I now fully believe that if I update the mid's in the Quartet they will far outshine the RF-35's.
