I am running 2.4s with a Manley StingrayII and it has plenty of power for these speakers. Much more so than the CJ CAV50 that preceded it. With 4 EL84s per side, this seems to be a "higher torque" design, especially given the 5 Ohm made in house output trannies.
Dalis or Thiels
Any thoughts on the Dali Helicon 4's mk II and the Thiel S 2-4 with mac equipment thanks
