@77jovian, Much of the recent amp discusion here has previously been disucssed here. Suffice to say that I doubt that the Ayre AX-5 twenty is up to driving the CS 3.6's or 2.7's to their potential. The steady impedance levels of these speakers are beyond the specs of this amplfier. Your old Krell KSA 200 would seem to be a much better match.
