Octave V70SE to drive Martin Logan Summits?

A friend had them, a Mac 275 would drive them but they are a quite difficult load. the efficiency is lower than MLs rating according to test reports I have seen and the impedance is very low in the high end.

As Al says, if A drives B it should also drive C does not always hold. I have Meridian 605 amps, which are 150 watt mosfets. They never had any trouble driving my Apogee Duetta Signatures, which are known as a difficult load. But they get very hot and have to be carefully monitored driving my Gamut L5s. Most would think the Apogee was the harder load but not for the Meridians; every amp -speaker interface is different.
