I have a chance to purchase a pair of Monitor 10B's locally. They are in very good condition and are priced about $180 which seems a bit high but with no shipping not a terrible price I suppose. I got to thinking about the various Monitor models how they rate. I imagine the earliest models with the Peerless tweets are best. After that which are most desirable? I currently own a pair of Monitor 7B's as well as Series 2 Monitor 12's and like both of those. Any thoughts? Thanks.
