60 dB is plenty. And works fine at 100 ohm. (Used mine initially with Vincent PHO 8 at those settings) Now using with Sutherland 20/20 at 60 dB. Tried at 200 ohm and then 475 ohm. I prefer the 475 setting because the midrange sounds a little more filled out. But I am told it all depends on the rest of the system also. Bottom line is it will definitely work fine with your Cary.
