I see that one loosely mentioned option for the Yamaha 9000 Pro is something called a "Home Performance Package", which apparently includes a keyboard stand, gooseneck lamps, and a speaker system consisting of a subwoofer and two satellite speakers. Anyone have details on what the speaker system's specs are ? Any online pix of it ? Price ? Also, has anyone found a good quality case for the 9000 yet ? That 16 1/16" depth isn't exactly a standard keyboard size I'm reckoning. Thanks again... Esh
