I have an almost BNIB (well no box since Patrick doesn't supply boxes with these) Zuki 6 Channel rated at (Zuki) 3wpc. Seperate power sections / supplies for channels A, B, C, D then E&F. FORGET the 3wpc and read some reviews. Pure class AB with provisions to do 3-way active off the amp. No noise floor like the class D amps. Pure SQ. I paid $375 shipped so I want $375 and shipping. I have new Zuki amps being built for competition only. Keep in mind that the 3wpc actually means 85-90wpc of clean power....closer to 100-125wpc @ 14.4 volts.
