One thing to keep in mind on the ARC pre-amps....if you are driving a subwoofer with your solid state pre, you're gonna be out of business with ARC. They say the impedance of most subs is too low, and that trying to drive one alongside a stereo amp will be deleterious to sound quality. Sad situation as I would love to try an ARC pre with my Rowland 625 S2.
