The MC 275 Commemorative came out in 1993 in a "limited edition" in honor of the late Gordon Gow, longtime president of McIntosh Laboratory. You can tell the MC 275 Commemorative by the plaque on the front. Frank McIntosh may have developed the McIntosh circuit, with a very young Sidney Corderman looking on. Gordon Gow looked on, too, and he, more than anyone, built the company.
