Good job grabdog! It was due time for someone to make a proper review on msur offerings. It is a puzzle to me why msur and rebrands are not the most talked about products on head-fi. People who don't like them so much still think those are a good value for $150(cheapest msur n550 rebrands cost about 70$,) When slightly modded and eq'd I think those can sound as good as $1000 headphones. It is a bold statement, I know. But I've been around the block so many times that I got the experience to trust my ears instead of the price tag. Since hearing is subjective I would propably start to question myself I'f I was the only one to like these headphones so much. Luckily that is not the case. Me, I prefer modded msurs's over t5p, oppo pm3, nad viso hp50, focal classic and pro...just to mention a few closed back headphones. Other people have preferred msurs over praised yamaha mt220 and beyerdynamic dt880.
