Well I don't post here very often but I like to spend time here and try to see just how much of your knowledge will rub off on me. I am currently running a ML Vignette, Center; ML Mosaics (2), Main L&R; Definitive Technology Super towers 7006 (2), for L&R side channels; Definitive Technology BP2 (2), for L&R rear channels and a Definitive Technology Supercube II Subwoofer. This is powered by two Outlaw 2200 monoblocks for the mains and an Outlaw 7555 for the remainder of the room. I'm using a two-year old Denon AV Receiver for a processor. I really want to upgrade the main speakers and then just move everything to the rear and retiring the BP2's to my new van project. I have been saving for a while and set out today for a visit to my buddy at Magnolia. I took two CD's with me, Dido's live at Braxton CD and the first CD from Wagner's complete Ring set (The first CD of 15 that make up the opera. To my total amazement, the VISTA was flat and dull and had boomy bass. I know you guys/gals must think it's me that's defective. OK, I give up, fire up the Vantages. I thought there were almost as bad. I know this is sacrilege but nobody is more confused than I am. The Vantages were run completly off of McIntosh and the Vistas were running off B&K, both good systems. I'm going back in a couple of days and try again. Both are newer speakers but I can not believe that given time they could change that much. Suggestions PLEASE! I thought I would have new speakers tonight!
