I have a PPI 2300 Limited Edition amp for sale. Its 2 channel. It has been used for a few months by me and the guy I got it from had it sitted in his closet for who knows how long. He said back in the day he had it powering a set of components. Great amp and very strong. Give best over. 2x75W @ 4 ohms 2x150W @ 2 ohms 1x300W @ 4 ohms bridged
