make sure your speakers are sitting firmly and spiked properly (or whatever Soundlab recommends). I recently put sound anchor stands under my Audio Note E speakers and the midrange gained a more 'solid' 'palpable' quality when it was slightly recessed and hollow before. BTW I do know Soundlabs are big stats but I imagine the benefits of proper stands could be similar.?
Also I would experiment with cables which are great tone controls just ask JA of Stereophile :^)
