I am looking at the marantz NA 7004 [Link: us.marantz.com]
as an alternative to the URC SNP. I haven't gotten my hands on either (of course) but I hope someone creates a 2 way module for one of them quick. The Marantz doesn't have a Video out but if the info can be displayed on the PTX3 there's really no need.

The menu structure will be the true challenge for the new pieces. The Sonos is very intuitive.
