Two CONNECTS or Wireless Option

I have a CONNECT that I use with my stereo set up in one listening area. I have another adjoining dedicated HT room where I would also like to listen. Thinking of the following options:

1. Simply buy another CONNECT, although it is pricey

2. Run RCA cables through the attic to the next room (painful to do)

3. Use a wireless transmitter like Outlaw Audio or Audiengine W3. Wondering if people on this forum have tried this.

Any suggestions?
