I'm mixing, recording and programming with NS10's for about 9 years now,
and I've never regret I bought them!
Shurely they suck; they mids are hyped, the lows are not there, BUT, they are really easy to mix with, you can exaggerate with reverb, with vocals, pretty much with everything; you don't have to mix carefully with these speakers.
Everytime I listen to a cd of Michael Jackson, Jodeci, The Beatles, Slayer, or Abba, I notice that the vocals are always very upfront through the NS10's.
That's why, it's quite easy to make a good mix, and not worrying about the vocals being too loud in the mix, or too much reverb being used, once you get to know the sound of these speakers.
I don't like 'shy' speakers, I want to have lots of headroom to play with, that's why I still use NS10's.
