Actualy, the top picture is that of the 2-channel epm-2150 amp, top left being the back, top right being the part that slides into the amp.
The bottom picture is the 1-channel monoblock epm-300 amps, 7 of them inside the chassis.
Here is a pic of the 300's in place with one being slid in...The MPS-1 with 7 epm-300's weighs over 115lbs. Each amp having its own power supply and toroidal transformer. Gene Dellasalla's review on Audioholics gave it very high marks for the quality of all the components and the best capacitors, not to mention how it performed at one of his relatives columbian party's.
