You listing your amps on Craigslist or some other listings? You have more channels in your system than I do. Mine is 5.1.4, so my MX-A5000 11CH amp has 2 unused channels. The MX-A5000/5200 11CH amp would fit your 11Ch-system just fine. :D I think I have a buyer for the 4BSST already, may have to list one of the preamp, likely the GFP565 first. Then I am going to finish the class A F5 before selling another power amp.
