Tweak, I think you are on the wrong thread.
kjack, everyone here has it pretty much right. Hold your tater (southern slang) or take a deep breath. Do not waste money on substandard equipment. Those are great amps for those speakers. You certainly lucked out on that deal. Wait until you can afford the right preamp. The Atma-sphere is fine. You might also consider watching for the right ARC to come up used. The fellow that passed on, what was he using. Had the wife already sold it?
