I may try it. I'm tempted to go full OB down the road. There were some things my old Maggies could do that were magical, but they were so limited by lack of extension on both end and no 'punch' (for lack of a better word) that I gave up. I'm hoping that the OB route may give me the best of best of both worlds. I was originally intriqued by the Visaton driver, but the Hawthorne will probably be my choice, if I go this way.
My Merlins are very nice, but they sound (to me) like good 'hi-fi'. With the right material, the old planars just sucked me in and sounded like music.
