Hi Wayne,Here's a quote from the circuit design of the amp taken from Nelson Pass's website (Son of Zen project):
"First, the damping factor is quite low, on a par with some of the tube amplifiers on the market. If you need an amplifier with a high damping factor, look elsewhere. You can improve the damping factor of the amplifier by scaling the resistor, but only at a heavy efficiency penalty."
