I have the NTK and the NT1000. Both have a lot of "air" to them and no, I don't think you can do the same thing by just eq-ing them. Maybe if you've got some really good equipment, but if you can afford that kind of rack you probably won't be looking at $300 mics. The NTK sounds a lot like the NT1000 but has more "body" to my ears. I think both can be used on the same sources. The NTK is just a little bit bolder. I found a place on the net that sold them for $386 and GC matched it. That's a lot of mic for under $400 IMO.
