This is my first attempt at wireless streaming after two years of cd listening. Right now i am using a Sonos Connect (formerly ZP 90) as a wireless streamer for aiff files on my office mac and then fed via coax to the w4s Dac1. The panels on the back are some basic Ats acoustics and under the amp and cd are some Herbie's Tenderfeet.
Nice, simple system beginnings or not. It is very similar to mine in terms of setup. I have been using Sonos for over 10 years for my whole house audio. I recently changed from using a ZP90 to a dedicated PC streaming music wirelessly from my NAS. I was very impressed with the improvement in sound. Also, by using JRiver Media Center software on the PC I could rate songs and do other music library management tasks that the Sonos interface does not offer which always frustrated me.
