Bvdiman,
I think the ability of the user to tighten the pucks on the back of the V2 and M5 has more to do with the movement inherent in wooden enclosures due to temperature and humidity changes. These built up Baltic birch ply enclosures move over time. The aluminum enclosures should move less with changes in humidity. I don't know about changes in temperature. The other concern is the movement caused by the massive pressure inside the cabinets created by the sealed design. One would presume that Magico did extensive testing in the area.
