The Soundstage review of the M40 mentioned a slight bit of vocal chestiness or heaviness when compared to the M3Ti, which I guess seems typical in the battle between monitor and tower. Would the extra driver of the M50 actually help out with regard to this slight problem or make for a harder- to- drive-cleanly speaker? Could this increase in heaviness be ameliorated by placement in a larger room?The partnering amp would be the 50 wpc NAD C340.
