If you are skeptical about doing a driver upgrade on the Monitor series, as I was, don't be. Because I had a busted mid, I replaced those (6502) and replaced the SL2000 with the RD0s (per engtaz and H9's persistent suggestions). Both are very easy drop ins even for one who has never done this (like me). The mid's connectors are not marked (not sure it matters, though the old ones had the red dots). But I must have done it right because the speakers sound excellent. At first I thought they were a little busy, then I realized I was just getting a lot more detail. This morning, I am hearing lyrics better than I ever have.....unfortunately, some went like this, "I am digging my grave with my own hands." I know a lot of forum members have done this, but this is encouragement for those of us who flunked shop class.
