I just finished up a home with 14 zones of Heos, all Heos Amps except 2 AVRs and the in-pool speakers using a Heos Connect. The system works amazing and the customer loves it. The only problem we have had is the 2 second delay when linking zones outside, (6 zones and 2 TVs). The unit with the hardwire connection plays whatever is on the TV no problem, but as you connect other zones, the delay starts to kick in. A recent update added TV Mode to the Amps and Connects, that helped a lot.
Just something to be aware of.
