Unorthodox Behaviour by Brand X and Moroccan Roll by Brand X both prove the quality of bass drum I have is up there with the best I have ever heard and one thing I don't want to do is to lose the rhythm and drive that this amplifier puts into the music but a bit more volume would be very welcome. At the moment my amplifier's volume control is on the ten to position and it is just a shade too quiet. If I push it much further than this I can hear it clipping or at least I think I can hear it clipping. I am very sure that I need some very efficient floorstanders to maximise the headroom and give more bass weight. Either that or I need to go back to transistors.
