This is a smart system, and sounds great, but not without the glitches one expects from pretty much every modern computer based network device. It seems to get confused when network sources last used are turned off whilst it is sleeping, for example. Needs powering off and on at mains to sort that one. The hairiest bit for me being its insistence on updating its firmware the first time I turned it back on after initial setting up. It tried to do this via the wifi connection, and failed. At that point it entered groundhog day mode, trying, and failing, consistently (a process of many many minutes, if not hours each time) to perform the update. Eventually it presented a fairly meaningless generic failure message. Nothing as straightforward as 'firmware update failed - perform a factory reset'. It did a passable imitation of an expensive brick at this point - scary for a little while. Having witnessed similar recently with a Yamaha AV amp I did some googling, found how to perform a factory reset and forced it to do a firmware update via wired connection before turning it off again. That resolved it, but it occurred to me that not everyone would be comfortable having to either do that, or even be aware that it was necessary or how to go about it. Great for the smartphone generation, but not Victor Meldrew - amazes me that everyone seems to accept that they (smartphones) don't work reliably and need turning off and on regularly to kick them back to life. Whatever happened to system testing...Rant over. Summary = it looks smart, sounds good but may need a little knowledge, and tolerance of its foibles.
