Hi everyone. I just took delivery of a Fosi BT20A Pro with a 48V power supply. My intended use is to power some ceiling speakers from a channel on a Nuvo multizone amplifier located in a cupboard. The Nuvo has channels with pre-outs, so I can control the volume from the Nuvo but I can't control the power of the Fosi remotely. I'm not too keen to leave the Fosi permanently on so I was going to put a smart plug behind the Fosi and control power to it that way. I read a review by someone on Amazon of a similar Fosi amp who commented that the power supply is always on and the switch on the Fosi doesn't actually switch the amp off but puts it in a standby mode. His comment was that switching the power supply on and off at the wall would shorten the life (not clear if it shortens the life of the amp or the power supply). Something to do with the inrush current?
What are people's thoughts on this? Do you see any issues leaving the Fosi on at its switch and switching power at the wall? I could potentially switch the power between the power supply and the Fosi with a smart relay, so the power supply is permanently getting power. Would that be better?
