Surprised this is not getting more attention. These sound amazing for the money. I have mine hooked up to an isolation transformer, which takes care of some of the main gripes people have.
ChrisNSorry, eh, a few benefits from it that you could mostly google. One of the grips you might hear is hum from the dual toroidal transformer, which is typical from dc presence in your AC line from other devices. An isolation transformer would eliminate that. Not sure I would recommend getting an isolation transformer, unless you have some extra cash to burn. I personally noticed a big difference, but my power was/is dirty.
