And the SA660 is 32.
Actually quite low for solid-state. Which indicates moderate use of negative feedback.
The Marantz 8B Tube amp has a damping factor of "greater than 20", according to the official Marantz spec sheet.
According to Locanthi's paper on the "T Circuit", the amplifier has a distortion of 0.5% before adding feedback. So feedback is not used as a means to conceal, correct or compensate a high distortion design. Rather, it is used to further reduce distortion and increase linearity in a well designed circuit.
