Hi Ken,
Answer: operate it wirelessly from the router. If both the RPi and router are within close proximity, then it's not an issue. I think it sounds better too, used wirelessly, minus any ethernet cable.
That's how I've been using mine recently, and I've had no problems. The only cables visible are the interconnects and (in this case very thin) connecting power cable, as happens with any other hi-fi components
In fact, in my current set up (used in conjunction with home-cinema system), the RPi is hidden on the rack behind my Sony AV amp, and connected to that with a 0.3m pair of interconnects (always use the shortest cables you can with the RPi, for best sound), so you can see hee-haw!
As an aside, I'd always recommend that folks fit a proper case to the RPi (I use the Pi-Case+, see here:

Oh, and another thumbs-up for Moode, especially the latest version with improved sound-quality kernels
Marco.
