I purchased this power amp a little over a month ago for $3K. However, I just sold the preamp that I had planned to use this power amp with. This unit is, as new and has only been powered on once in my studio! Off work on Unpaid medical leave so I’ve priced this ridiculously low for a quick sale. (Rack in photo not included in sale) Damping factor of 5000 and all of the power you’ll ever need in a 17lb package. Features both RMS and Peak Limiting simultaneously which lets you get the the full potential out of your cabinets without over powering them!
