On some of the BMW forums, I have read good and bad about the MB-75. The "bad" mainly dealt with the durability of the unit (i.e., it keeps breaking down all the time), the speed at which the changer changes CDs (slow, about 20 seconds), the 2V preamp outputs, and the fact that "random" play only works only with all six discs and not with just one disc at a time. The "good" mainly dealt with the convenience (I'll admit -- having six CDs and not having to worry about a magazine is almost tempting me to ditch my Alpine in-dash 3CD head unit) and the "famous" (or is that "infamous"...or maybe it's "legendary") Nakamichi sound quality.
