Interesting. I would still prefer the Squeezebox. My server computer is in the basement, running full-time. I never need to go down there because I manage it remotely using VNC from another computer when required. I don't want a computer running in the same room as the stereo if I can help it, and do not see the need to have a full screen open to access the music. I find the little Squeezebox client to be just fine for accessing the music. Where I think we also differ, is that I have a wired ethernet connection from my PC to the Squeezebox client - I found the WiFi painful with drop-outs and clearly inferior sound, particularly with full resolution wav files.
Since you are happy to run wired connection to the Xitel and then to the stereo Harry, why not try an ethernet cross-over cable from your PC to the Squeezebox and see how the sound/performance is then?
