For what it's worth, I'm currently listening to a pair of L500's. Unlike most people here, who seem to have bought and sold theirs, these are original, with no changes. As far as I can tell they are in perfect shape. I bought them in the early 70s when I was in grad school. They were originally driven by a Dynaco Stereo 70 and whatever model tubed preamp went with it, modified by the store where I got them. Currently they're fed by an Arcam AVR-250. (Unfortunately the old Dynaco equipment doesn't do very well at decoding digital inputs, which is all I have these days.) Space doesn't allow me to consider anything larger. (I just happen to have these set up at the moment. Typically I use a pair of Paradigm Studio 20's. It's not clear which is better. Measurements suggest that the L500s are flatter.)
