I’ve been using my naim unity star for over a year and had several firmware updates. With the latest update to 3.4.x the unit ran into a fault 3 times in 2 days. It won’t respond to the app, remote, or unit itself. I can only unplug the unit for a reset.
If you have not done so call or email Naim, this did not occur in beta testing of the latest firmware. If you can send a screenshot and as much detail on what happened and what you were playing, server, tidal etc so much the better.
My unity star was trialled for the last week with a HDMI TV connected to it. The fault could not be reproduced in the audio studio store. I had about 4 freezes prior sending it to the store. I was informed that naim was aware of the faults and is working on a new firmware version. The previous firmware was restored and after 6 hours of playing I had no issues so far.
