The sound is what Amps are all about. I compared this to a much older Stagg 150W Monitor Amp. The Stagg has better Bass, better treble., more Clarity from Drum tracks, Cymbals without Sibilance and a generally clear sound. On this Amp with the treble turned all the way up it still didn't come through on the high notes. Strangely enough it did score well on female vocals. The Bass is Muddy/Mushy. In summation, seems to be well made, well appointed but Amps as I said are about sound, and this is a poorly executed item. Lastly while soak testing the power supply ran very hot with no sound going into it. Shame
