Your idea of a MUSE EIGHTEEN is an excellent one, they make personality cards for the Martin-Logan line. The Muse has been a top choice since it's introduction in the early 90's, a Stereophile Class A recommended component for many years,(dropped only as policy of Stereophile in not having been reviewed for a period of time) and is STILL UNSURPASSED in it's performance. Put most simply--"IT'S EVERY THING A SUB WAS MEANT TO BE." One problem with the Eighteen. With the exception of one I recently saw in the Audiogon Classifieds, you simply don't see owners putting them on the used market very often. Maybe this speaks volumes about the product?
