***Disregard if you don't know what a GUI is (like whoever coded this interface. No customizable menus. No widgets far as I can tell. Twisty and archaic. But overall functional and not bad! - speakers lose sync sometimes .... if u have a wireless sys; you shouldn't ever wish you "HAD WIRES" Great hardware tho, far as I can tell. But for real, honestly people, we all need to start demanding more from our GUI's.
