Up for sale is my Audio Design Associates (ADA ) Power Amp model MPA-501BA & MPS-500 Power Supply. By separating the power supply from the actual amplifier one can reduce the noise from the power supply. One can also turn off the display to the 501 to reduce any noise from it.
This was ADA’s former Flag Ship power amp until it was replaced by MPA-5500 Flag Ship, which has a detachable cord and inputs for XLR. I’m selling it, because I live in a multi unit build and my neighbors don’t like me playing my home theater too loud and I’m emphasizing the stereo aspect of my system more.
Condition is conservatively graded at very good. There are some slight scratches on the top of the massive units, but don’t affect the sound quality. These things are like tanks and can be run long hours without any issues!
