Hi Sarcher30, thanks for your responses. I currently have the Cary 805s. I think the efficiency is rated at 91 dB.
Martin Logan Summit X with Cary Audio 805ae
Does anyone have experience with using a pair of Cary Audio 805ae monoblocks to drive a pair of Martin Logan Summit X loudspeakers? I'm concerned this combination might not work that well given the low impedance values of the Summit X loudspeakers at higher frequencies.
