Any one has both? How do they compare? I realise one is open and one is closed, but they cost about the same and the only thing that matters for me is sound quality. Specifically, with regards to their scalability to higher end amp and sources in details/texture and transparency.
One has proven relatively long track record in its scalability, the other has a lot of hype relatively recently.
I have seen a few brief comparisons here and there, however none seem to be done with higher end amp and sources, which IMO doesn't really tell me what they can really do.
