tschanrm and hershey, thanks for the replies. I'm mostly interested in listening via digital inputs. I'm thinking of replacing the XR10 with the F10s solely for the increase in digital inputs. But, I'm worried that I won't like the sound of the F10s as much. If I can get one brand new for $150, do you think it's worth it? How do you like the auto speaker setup feature (clap your hands), the digital equalizer, and the All Channel Stereo modes - Are they all hokey or are they worthwhile? It seems the digital equalizer along with an SPL meter would be very useful. Also how do the remotes compare?
