I was in the studio last night/this morning and one of the cat's that is doing some of the gopher duties (getting our crack, brown m&m's and bitches), is a power amp guru. He mentioned to me that when ever you are picking a power amp, make sure to look for Damping/dampening factor . The higher the number the better your low end response will be. Is this true? What is the Damping/dampening factor?
