I don't know. I would hope so. And the IMD issues too. Both matter to me, even though I'll use the CS Labs cal file, I would feel much more confident knowing both cals were very similar. Then I could be sure the mic was dead on.
I bought it because:
2. Has better low end (<20hz) than my ECM8000
3. Two mics are better than one.
So I should still be fine, but would appreciate having a clean and linear mic rather than a mess that is "fixed" by a 3rd party cal.
Either way, another big props to Herb as CS Labs. When I get my mic I'll test some speakers and see how it goes.
