Great question! My setup is very similar to yours, except i have an Apple Lossless library on network storage. I arrived at the Mac Mini after stepping away from a Sonos setup with a desire to try some higher resolution files. I first tried the PS Audio PerfectWave and Bridge, but didn't care for the way required the server side to be setup. I too have been curious about the Bryston player and would have no problem moving my library from network to local usb storage, but if Sonos were to begin to support higher resolutions, i would probably go back to their way of doing things.
