ha ha dont even try to run NS10's off of something like that. Not saying that they wont work, but those amps are great for big P.A. speakers, not studio monitors. The last thing I think of when one mentions crown is flat. There is a crown amp in the PA at my studio but I would never think of hooking any of my speakers to it.
There is a real big difference between any high end hifi amp and a p.a. amp, mainly in noise, dampening factor, ch crosstalk, stereo image, most if not all audiophile amps also have minimal circuitry in it meaning no gain adjustment, no limiters, just running full on all the time. They really need an amp thats has a high dampening factor, and real class A A/B circuitry in it. If you really want to hear the NS10s the correct way get a Bryston 4b if you can afford it. Like SS said If your on the cheap try to find a ADCOM GFA-555 either a I or II. One of the best sounding amps under a $1000. Period. I have a GFA-555 II's with some basic cap mods done just due to its age and it kills my 2b that now just collects dust. But I will admit that the 4B either new or old, are really good amps one of the best ive heard besides some older McIntosh amps.
