i just bought a pair of ATC 20T, low efficient 83 db. althoug they sound great but they very diffiuult to drive, any amp recommendation? a friend told me that only class A amp not class A/B amp can handle it, is this true? thanks
Timchen, you would need a HUGE amp if it ran only in class A. Why not try ATC's own integrated? I heard ATC passive and they sounded better with the ATC int. than ATC active 10's.
