Coincidentally, I recently picked up a pair of a/d/s L420 bookshelf speakers on ebay for a secondary system. I was drawn to them due to the great sound that my a/d/s L610 floor-standing speakers still have 22+ years after their purchase. Though not as full-sounding as the L610s, the L420s still sound very good, with a clean, crisp sound comparable to the 610s. Do you also happen to have the L420s, Dan? And did you ever sneak the sub-woofer in to the garage? (I'm thinking that one would generally go un-noticed behind the couch...)
