How much damping factor you need depends on the speaker you intend to use. Some speakers are specifically designed for use with tube amps that generally deliver low damping. Coupled with an amp with high damping factor will produce an over damped bass response, dry and muddled. I think it has to do with the Q factor of the woofer. Maybe someone out thier in Audiogon land has a better grasp of the tech aspect.Suffice to say, matching the right amp to a speaker can make a huge difference.
