SMPS idle whine probably. A lot of phone chargers are really bad for that so I can't have them in the bedroom, but the Audiophonics seem to be at a very low level in this respect and I usually have them on when in the cinema room.Yesterday I noticed by chance that the amp emits a relatively low-level, but still audible (when putting my ear right next to the amp) high-pitched "whining" noise when switched off. When I turn the amp on, this noise stops and is replaced by a lower-frequency noise, again not very high in level. Nothing major, but I was wondering what's going on there and if there is any way to get rid of it altogether?

I also have them powering off physically when not in use via triggers so it's never an issue.
