Sorry if this has been answered already...
I see that the vertical pole is 40.64cm in height, but I'm wondering what the exact measurement is from the center of the middle mount to the base when the stand is fully vertically extended.
I have a fairly large headphone amp that I'd like to be able to slide underneath and still have enough clearance that heat from the tubes isn't an issue.
darcyI measured a little bit below 42 cm (not including the thickness of the base). It looks like the center of the mount sits approximately level with the top of the clamp that attaches the arms to the pole. It is hard to tell for sure though since the center of the mount is a few inches away from the pole and has an arm in between.
