I have a set of Klipsch ProMedia Ultra 5.1's in my basement that the amp blew out on (again) but don't have the heart to get rid of them yet. I dont know if I will ever fix the amp, but I always have that "maybe someday" attitude about it.
I am using some M-Audio av40's I picked up for free. They sound ok, but don't have the impact of the old Klipsch set.
I loved my av40s.
