After years of happy listening I turned my nait5i on and the motor on the volume control will not stop trying to lower the volume.
The volume buttons on the remote control seem to have no effect. I have shielded the IR receiver on the amp in case another remote controller in the room is causing the problem.
My next step is to take the amp to a dealer and I fear that they will need to send it back to the factory.
If I lived in the UK I would without doubt return the unit to the factory and I am certain it would be returned as good as new. However, living in Germany makes shipping out of the EU problematic.
Since the function of the amp is unimpaired I am tempted to get my local flagship NAIM store to simply disconnect the power to the volume servo motor. I hope I am not being heretical but at least this approach uses qualified technicians and it is practical.
