A while back, I built two AV15 subs using identical alignments. One is powered with a PE 250W plate amp, and the other with a rythmik 350W (380W?) plate amp with the TL072 upgrade. I've noticed that the two amps produce very different results when they clip. Playing the PE amp at levels that absolutely MUST be clipping only produces moderate distortion that makes things sound "funny" or "somewhat wrong". Clipping the Rythmik creates a loud POP or CLACK sound. It's scary... makes you JUMP. Does the PE have "soft clipping" or something? Why would these two amps behave so differently when they clip? If "soft clipping" is the answer, can it be added to the rythmik amp? If so, are there drawbacks to doing so? Perhaps losing some dynamics? Thanks!
