I actually use 45' cables between my front amps and my 1050. I bought them from Markertek. They use Canare cable and connectors and they sold them to me for very close to what it would have cost me to make them myself.

As far as the wireless audio distribution. I tried that about 2 1/2 years ago and was very dissatisfied with it. Perhaps the technology has improved but my experience was decidedly negative. It was not even to the level of entry mid-fi in my estimation.

YMMV.
