@georgehifi what would you recommend for YG Hailey 2.2s
Sorry Keith, never heard them.
Also from what I can find, no "independent load measurements" has ever been done on them to see what kind of amp would really be suitable.
They apparently dip into 3ohms, I'd like to see where? and for how long?, also if there's high negative phase angle also at that frequency, they can easily start to look like 2ohm or even 1ohm to the amp.
Safe bet to run an amp like the Gryphon Diablo into them or a cheaper Parasound Halo A21+ or Halo JC1's if you can afford them.
Cheers George
