If you look at some of the amp porn over on avs you will see the internals are different. It is quite clear that a number of the newer amps are clones of designs from more established companies like Crest or QSC.

The EP series is a clone of Some QSC amp. The Marathon 5050 looks identical in layout to one of the Crest Amps.
