Review from a 1995 Stereophile review written by Robert Harley:
"Conclusion - The best word to describe the McCormack Power Drive DNA-1 is "musical." It consistently offers an involving, satisfying musical experience. Apart from the specific performance attributes detailed in the body of the review, listening to music through the DNA-1 was just plain enjoyable. This is one solid-state amplifier I could be happy with for a long time. Further, the DNA-1 represents an extraordinary value; this combination of musicality and sheer output-power muscle are unprecedented at the price, in my experience."
