Stevenj, I cannot tell if your post is in jest, or you are sincere. If you are suggesting that lowering and raising the damping factor with a switch is a joke, I can assure you that it is not.
Controlling an amplifiers damping factor is not novel. The Wolcott Presence amplifiers have had this feature for two years. The user has easy access to a toggle switch for both high and low position, and a rotary knob that adjusts within each range. Adjustment of these controls provides performance changes that are not only easy to hear, but at the discretion of the listener.
The man who invented this product is an engineer who values specifications, but is also aware that the reproduction of music is an art as well. If it is of any interest to you, the switch changes the positive control feedback voltage internally, without affecting the load to the output transformer.
