hd660s2 vs hd650 vs 600

Just another 2 cents: for me the price difference between the 660s2 and the 600 was like 180 euros. Since the 600 were praised so well in general by many, I figured that 660s2 wasn’t worth those extra costs, although I understood from Sennheiser that they are build with way more complex technology.
