No comments yet on that webinar presentation! I watched it but most of it was far too technical, at least for me. However, I still want the M33 in my system as soon as it becomes available.
I asked whether the suppied microphone was calibrated but the answer was simply that it was "accurate". In my view, if room correction is to be based on measurements taken by a microphone, that mic MUST be factory calibrated with its indivudual calibration table either downloadable from the manufacture's website or pre-loaded into the amp. An "accurate" mic is likely to be no more accurate than the speakers being measured, specially if the speakers themselves are sold as "accurate". What's the point of matching your speakers / room acoustics to a micrphone's curve that has lumps and bumps? The mic supplied with Martin Logan's PBK kit is at least properly calibrated once its curve is downloaded into the ML / Anthem software.
