What is good about binaural recordings in my opinion is the good mono compatibility (tried it with full orchestra too, for full spectrum music. I couldn't detect any relevant cancellation).
Another thing that isn't usually mentioned is that by the nature of the technique, especially if you use ear canal replicas instead of just the outer ear, the S/N ratio gets increased by the amount of gain introduced by the frequency response of the ear/canal combination.
We are talking about 15-20 dB increase or more of S/N Ratio, A-weighted.
This lets you use smaller capsules with worse SNR but flatter frequency response.
My custom made binaural microphone is finally ready after more than a year in the makings.
This time it went under a full restoration, with better capsules, better preamps and most importantly, a new set of ears, with anatomically accurate ear canal replicas, which is something that not even the Neumann KU 100 has.
I'll post results when I get a chance to record something.
