I know the transformer is not shielded and there is not even a heatsink to use as a barrier, but I really hear no hum at all. Maybe some people will? I guess the sides of the case are used. for the heatsinks. Or maybe there is another layer of metal on the sides for it, hard to tell.
I do not know what size the transformer is. Do you know? I am not sure if that would fit into a Brio-R's case or not. Maybe I need to open it up and take a look.
Don't open it up, don't bother about transformers, enjoy its purpose.
Did you test it with other speakers than the ProAcs?
