Lewm, thanks for that, and your points are well taken. A step down can certainly do the job, and with the added benefit of isolating from the mains.
A glance at his system page suggested to me that the OP is a pretty sophisticated audiophile. I figured he knew about step downs, which are not esoteric, but perhaps not the Monarchy, which is a pretty nifty gizmo--and cheap for its type-- that not only regenerates the AC but can step it down (and change frequency) if one wishes. Just trying to add to the info pool.
