I decided to test the frequency response of the mic-in and line-in inputs of my Tascam DR-2D.
First I generated white noise (in a 24 bit / 48khz aiff file) in Sound Studio, and ran a Fourier spectrum analysis on it:

I then played this signal back through USB out > Lyrix Headstage > Tascam DR-2D at 24/44.1, either mic-in or line-in.
Both mic-in:

And line-in:

Appear to have pretty flat frequency response.
Please let me know if you see any flaws in this methodology.
Edit: Low cut set to OFF, of course.
Can you zoom in? The DR-07 test was done with a very fine grain scale. I don't expect it to change much/anything, but it's something to consider.
Looks good to me. Thanks for the test, I can sleep better tonight.
can you make some tests with low cut filters?

I don't think I can change the scale with the software I'm using, but note that the grid lines are 5 dB apart, same as the DR-07 test.
I'll run a test with roll-off engaged tonight.

And record better tomorrow. Ditto, thanks for the test. +T
Thanks. This recorder has become rather appealing now that the price has dropped well below that of the M10.
Thanks for the note about price. B&H Photo Video has the DR-2D for $147.
