Aesthetix Io transformer noise

Calling Aesthetix Io owners. How normal is noise ( a constant buzzing sound) from the transformer in the power supply ? Should it be audible 5 ft away ? This is a new unit with barely 20 hrs on it.To hear anything from the transformers on my Parasound JC1s I have to put my ear up against the top plate and then only faintly audible. Experiences will be greatly appreciated.
