Nope. You get what you pay for. If you think you need that kind of performance you want 8717s or BLS 451's

If you want good ones for less money get the 9452s

If you want pretty good ones get 9252s

FWIW I threw my 600n that I got in a trade together with 9252s because I have a drawer full of them. One of the pro's flew it and asked if I had 8717s in it.
