I have the H160 and it does tend to disappear as a target on the iphone 5s but it seems always show as available on the Macbook pros in my home. The only real issue I have with my Hegel is the volume. It uses the volume limit of the Airplay device, which often times is set way to high for the H160 and my bookshelf speakers.Short of adding a separate streaming device and giving up the Hegel internal DAC, I see no way to resolve that. But ultimately I fear I am going to have to go there before someone damages a driver on my SF Concertos. I'f you could just set a switch on the Hegel to never exceed ... like 68, it would not be an issue. The good and bad of integrated ....
