Mrg7- while Jfrech is technically correct, there is more to it than that. I don't know about the truth of the statements, but 12 db addtional gain is a lot. Some (most) pre-amps volume controls are non-linear in gain and also non-linear in sound. So if you have to operate your pre at a point where small movements in the control produce large changes in volume it may be an annoyance and have a detrimental impact on sound. This is whys some preamps (like my ARC) have user adjustable overall gain. It can be a problem, but is highly user specific.
