I will chime in again, i bought a genz streamliner 900 a few years ago and to me, if it really was 900 watts, they were pretty small watts.......i then bought an early markbass little mark 2 which in my opinion is as powerful as the genz streamliner 900.....I then decided to buy the markbass sd 800 (earlier class d ) and found that to be similar, lacking the warmth of the little mark 2.....Also tried the later little mark 3 and i find the tone of the mark 2 better.......So the LM 2 is staying put for the time being!
