In the early days of tube stereo products, McIntosh was 'it' in terms of reliability, low distortion specs., the Mac clinics, as well as visually with their characteristic glass face plates. They were second to none until Marantz showed up and gave Mac a run for their money. McIntosh has a following just like any high end audio manufacturer. Their products, generally speaking, are built to last a lifetime. Just like other manufacturers they have hits and misses. In their day they were considered the Cadillac of audio gear and many still feel that way.
