the only reason the NS-10 is considered "industry standard" is because when they were made they gave hella sets of them to like every major recording studio in the country. If you actually gave those things a listen youd find thay have a piercing mid range that will slice your throat, they aren't that good at all. The frequency responce chart on those things aren't balanced at all, IMO those speakers really suck.
This is a matter of personal opinion but some of my favorite monitors are the Tannoy reveals, Event TR8s, and a 10 inch genelec that i can't remember the name of. It all depends on what kind of music you are mixing and what frequency ranges you are looking to monitor. If you are interested in the NS-10 yamaha is currently making a new line of speaker that were modeled off of them, 2 reasons they don't make the NS10 anymore 1 they gave away a set to almost every commercial recording studio kiling their market and the PAPER yes PAPER the cone is made out of is now an endangered tree and they couldn't manufacture them anymore. thats at least what i heard.
