Here are some general guidelines for choosing an external mic to pair with the DR-40:Sensitivity:....less than -50dBV/Pascal -- noise is obvious/intolerable -- most dynamics fall into this category.....between -40dB and -50dB -- noise is mostly unnoticeable....greater than -40dB -- noise is a non-issue -- most condensers fall into this category

the DR-40 doesn't have much to offer there, but this was a non-issue for me

This is a non-issue to me generally but the first time I noticed

On the other hand, you have a condenser mic, the noise is a non-issue.

The fidelity is worthless, but I always check recordings through headphones anyway, so this is a non-issue for me

I want to like it, from reviews I

This doesn't sound like much; after all, I think that correlates to moving back about 1 meter during recording (presuming sound moves at 343m/s, the delay of .003 sec corresponds to ~1 meter)

If you're doing recording on those neat U-shaped rigs, this mounts nicely on top to capture that sweet audio.
