an informative article...
No so concerned with ground loop noise, or should I say yet. It's an issue I can handle if need be.
Cross-talk would be an issue if I could hear the phone ring through my amp at a Gazzillion dB! Might even make an interesting 1/2 hands free phone.
Won't be sharing cable though.
The reason I was even thinking of it, was that all of the MP3 network devices are poor quality, and ad-ware based software. I got one and it is driving me nuts. Tries to sell me stuff everytime I start it up. Also doesn't operate from any other of my audio programs. I can listen at the office from the speakers there, but sometimes nice to listen from the living room, on the big amp and speakers. (Rotel, and B&W)
They do make a connector for this: http://www.levitonvoicedata.com/catalog/BuildPage.aspx?BuildPageID=8
I was wondering about distance, but noticed that these connectors double up two pairs. Which could help out on that.
I'll let you all know how it goes...
