Spotted this setup...with the SB2, on the MLO's website...with picture's. 
Interesting that he said ...
"On a whim, I tried a hardwire ethernet connection to the Squeezebox2 (vs. wireless), and WOW... what an improvement! Far better imaging, tighter bass, and shimmering highs. In retrospect, I never realized what I was missing. I'm not sure why there is such a difference, but I suspect it's related to the four 2.4 GHz wireless phones we have in the house"
but later ...
"Finally had time to conduct a true blinded test... created a playlist of three "revealing" tracks, listened for 10 trials, while somebody randomly switched Squeezebox2 between Wired vs. Wireless B. I scored only 40%, proving (to me) that there really is NO difference between the two."
Good news for those of us with room setups not easily hardwired.
