I did a search on the Octave forum for Martin Logans, several Octave owners have tried them. ML Aeons seem to be a good match.

IMHO, if I could drive B&W N800's with Octave MRE130's, you should be able to drive the ML's. Make sure you do gte the Super Black Box though. It does make a difference.
Here is what I found on the Octave on the Octave english website about the V70SE:
"The V 70 SE, as all OCTAVE Amps, is based on the enhanced pentode configuration. This configuration ensures the absolute stability of the amplifier against the unstable impedance of the speaker. Impedance mismatch is without consequence, as the amplifier is stable down to a 2 Ohm load. An important contribution to this stability is the Single Impedance Output Transformer.
Power Output 2 x 70 Watt into 4 Ohm
Frequency Response 10 Hz - 80 kHz / ± 0,5 dB
Total Harmonic Distortion < 0,1% @ 10 Watt into 4 Ohm
Signal-to-Noise Ratio > 100 dB
Input Sensitivity 120 mV
Minimum Speaker Impedance 2 Ohm
Al,
I have chatted with you in the past about Octave products. Here is a link to the user manual for the V70SE with lots of specs:
