Can I jump in here with a question about low-powered amplification? I recently upgraded my makeshift center-channel speaker from a Totem Acoustic Mite to a Von Schweikert VR-1, now I'm thinking of switching monoblocks to drive it. I'm currently using a Marantz MA-500 amp, which kicks 125 watts. Suddenly I've been thinking about a tube mono or something, but that means maybe 45 watts. Will that be enough to push the VR-1? I've read that it is a pretty "efficient" speaker, but maybe I should just stick with higher wattage? I've also thought about going bigger with an Outlaw M2200, though the sale just ended. I do everything on the cheap, so I have to strike when I can catch a deal.
