ronboco, I use WiFi and can see two possible problems. One is interference. There is a dozen of channels at 2.4GHz, but you can only have three non-overlapping and I had dropouts. I switched to 5GHz and it is fine now. The other problem is delay. Music is transferred in packets and plays with a couple of seconds delay. When playback stops it keeps playing for couple of second from the receiver's buffer. It makes no difference, as long as all music is delayed. If it is only for subs it has to be time aligned.
