I've owned the 402 and really loved the amp. But my wife and I together can barely handle the weight of 402 and I don't want the hassles of preamps and extra cables. I was hoping to hear that the new MA 6600 was an improved product over the 6900, perhaps simply a C-45 & 402 packaged in one box with less power. I'm in a smaller room with a modest speaker load so 200 Mac watts are enough for me.
