It's a good question - I don't think there's a currently a competing headphone in it's category (Portable, closed back Planar Magnetic driver) that's been as well received, other than perhaps the more expensive Audeze Sine. The main thing I'm worried about is the ear pads perishing over time - replacements will be quite difficult to find I think, once Oppo close up shop.
