Morons! lol!
Oh man.
First of all you're not playing music though the cable your streaming data. And data is digital. The packets are either there or they're not. And if they're not there it will re-try at such speeds that you wouldn't notice. The music will still sound the same.
And if your network connection is so crappy that you ARE noticing lag or choppiness on playing back streaming audio then you need a $40 Gig switch or perhaps even a new $5 CAT5e ethernet cable from your local Best Buy.
More proof that audiophiles and computers don't mix. They're still living in an analogue world.
