Center Tapped Isolation transformer (60-0-60) with center tap connected to earth ground - balanced power for the audio gear... (I'm assuming 120v mains here)

Faraday Cage ??? ;^)

acoustic noise or electric noise...  
PS I'd build underground... it is much easier to get isolation that way...

Only good if you are willing to use lots and lots of capacitors to kill ripple, or else the diode commutation is actually worse than the 120V zerocrossing (look at the shape of the FWB diode "notch"... Tried this. I'd go with 120V lighting with enclosed fixtures, and all wire in metallic conduit. If you must dim usew an autotransformer (variac) outside the room.

Of Course...
