Basicaly my amp has died. It has quite a few faults, I am going to give it a good clean inside but if that dosn't solve it I need a new cheap amp. How bad are the Acoustic Solutions SP101 amps? I don't use the speakers that much and I have a trusty old Rotel preamp for headphone duties. How much can I get for my Marantz PM6010OSE in its faulty condition? Basicaly there are balance and input problems with it.
