(Note: Although we use Audio Precision instruments in the testing of our designs, we believe that listening is a much better way to “understand” our designs than is reading specs. The artifacts that you don’t hear with our electronics will tell much more than any spec sheet possibly could. Thus, we have kept the following specifications to a minimum.)
