Powersoft K3 DSP+AESOP Power Amplifier - Unit is in excellent shape and has remaining warranty period of (4) years. Unit is 1U and approx 17lbs. Amplifier has both voltage and peak limiting that is user configurable with downloadable software from Powersoft. Damping factor on this unit is 5000 which gives the amplifier heft & “slam” comparable to the coveted Crest CA9! These sell new for approx $4700.
I purchased the unit new from an authorized Powersoft Dealer. Love the amp but I’m going back to a standard all in one head.
