I have the NAC272, and for a long time suffered intermittent loss of the internet radio. Occasionally the signal would vanish after 10 minutes or so, and after pressing ‘play’, or the station preset, it returns — for another 10 minutes or so. Infuriating. Other times it works fine without any problem for hours on end. I also have a Uniti Qute, also a Denon streamer in other rooms, all of which are wired into the same network (fibre optic 70Mb broadband), and both of which work 100% of the time with no problem.
Has anybody else experienced this behaviour?, my instinct is that it’s a problem in the 272.
