To be honest, my first impression is that you're used to Cerwin Vega speakers which will fill a room with noise, but not especially good noise. They're boomy and loud but they way over accentuate bass and mids, totally sacrificing highs. What you are hearing now is most likely far closer to how the engineer intended the recording to sound as CV's are not especially good speakers, but you've grown used to the "wow" effect of having massive woofers engulf the room.

But that's just a guess.
