Excellent headphones for a price

Ok, setup: AK4497 DAC, Shiit Magni Uber headphone amp. Generally fairly faithful representation, good nuances, reasonably wide stage for closed cans. Sound fairly dark though, which is semi-expected, but certainly not for mastering. Excellent sound isolation, nice fit. Excellent quality, nice, sturdy, good cable. Could take one star off for a bit dipped mids and highs, but to be honest nothing to complain, really. These are good headphones, period. Excellent, given the price.
