Its likely the speakers. Years ago I had the BP...somethings (the biggest floor standers at the time around 1991). They were very "big & powerful" speakers, but to me the bass was way too bloomy and the midrange unrefined. I went the opposite direction and purchased some ML electrostatics and was very pleased with how much the music opened up. You may want to consider some planner or electrostats, unless deep bass is your preference.
