The 861v2 I had was much like that. Space as far as the eye could see, almost. I wonder how much that is true for the current stuff as well especially if you ignore the LPSU side of things. My old HD621 and 271s are certainly very light and the size of the 218/210 makes me wonder if it isn't technology that has enabled them to be that small but if things were always that small but with bigger cases.

Not that it is particularly important I suppose in the grand scheme of things as it is the sound that matters. Could be interesting to see what a 210 with a LSPU in a MS600 type case would sound like cost wise though.
