So many changes I've noticed to the ep500v2 amp. First the 3 accessible round fuses were omitted, then the crossover was changed from bypass (100hz) to 150hz, then the volume level knob was desensitized (is that a word?), then the replacement of the trim knob with a subsonic switch (which the older ones already had the subsonic roll-off program built-in), and now a totally new look for the amp, which now requires an rca-phono adapter jack that plugs into the xlr?
