Those of you who love deep bass and/or organ music must get Reference Recordings Crown Imperial:Festive Music for Organ, Winds, Brass and Percussion. I have played other organ and deep bass recordings with my Force XL before but the quality of and quantity of deep bass on this recording is unsurpassed. Not only is the bass very deep but the physical force of percussion and organ makes me laugh it is so strong. The recording does a great job of reproducing the acoustic of the hall, especially as the organ tones roll around the auditorium. Particularly impressive is the title track Crown Imperial by William Walton. I can only imagine what it sounds and feels like on a system with a Maestro.
