Have you tried the crossfade lp? if so what is your take on those?

Nope, never had a chance to check those out. From what I hear they aren't quite as impressive as the M-80s. Which is too bad because I would love to have the M-80 sound in a bigger circumaural frame.
there has been talk of an M-100 coming soon. I don't know any details at all, but perhaps that is what it might be. And there is also the Crossfade LP2, so maybe that will be similar to what I'm imagining.

M-100 is coming... I'm listening!

Thanks for the heads up

Good review. Shame about the apologetic tone but I guess it is hard to honestly criticised a products when it is a gift from the manufacturer....
