I dispute that's a "clear difference". They show near identical character and the differences are probably well within pure statistical variance given the nature of the measurements. That's why I posted them side to side to begin with. You can also go check out the
Stereophile measurements of the Metas, which are compared to the originals throughout. Darn near identical.
I respect the input from people that claim they can hear a difference. I don't. But I think -based on the measurements- that claims the old ones totally suck and are "unlistenable" is going comically over the top. If you find the old ones terrible, the new ones must be, too.

In no way ever enough of a measurable difference to make the originals bad, the new ones brilliant (sorry Amir :-D).
