Well the Sonos Play 1 is not a radio as far as I am aware (it's a wireless speaker) and also costs quite a bit more. I also don't have one to hand to compare, but if you are keen I am sure you would be able to find a store with both to test, like a local John Lewis or Currys where they will stock both.What is sound comparison compared to Sonos Play 1
How does one instruct the radio to turn itself off in a predetermined amount of time and what are the options for the amount of time that can be selected? Does interacting with the radio whilst it is waiting to turn itself off, for instance adjusting the volume or changing station, interrupt the sleep-timer mode so that the radio has to be reprogrammed to switch itself off?Not sure I follow what it is you want me to do exactly. Let me know and I'll test for you while I still have the unit.
