melody 2a3 mono amps
i have 2x melody 2a3 amps plugged into sonic frontiers sfl2 pre amp both are tubed. speakers i run are paradigm studio100 ref with a sensativity 94. plenty of power at 18 watts from melody's...problem is there is very little bass. not enough to make brass sound like brass the sound stage is way behind speakers(very good)cymbals sound like steel. doesnt ring like brass and so on .should i change speakers or amps or..........
