We tried it out with my stereo, and were able to easily get a reading of 70db with an indicated amplifier output of less than 10 watts/channel (maybe closer to 5 watts/channel, but I don't recall for sure). All this through my Infinity RSa loudspeakers, which I never thought to be particularly efficient. Now maybe we weren't operating things properly, etc., but I suspect it may have something to do with the small size (8'x16') of the room. Any theories? Sorry about my earlier comments about cow colleges. Some of my co-graduates took offense. We get by. Marion Hakanson {tekcad,teklabs,hp-pcd}!orstcs!hakanson
