Rick!
2.5us=0dB, 5ns=-54 dB, but the hearable part is ~12 dB lower (400kHz/20kHz, linear power distribution). Maybe 6 dB lower or higher, it doesn't matter, it's too much all the way.
I didn't care closed loop bandwidth. The gain of the closed loop (at ~10 kHz) is what counts. (It's a simplification, I know, but it doesn't worth the effort of the exact calculations.)

Tamás!
I think this specification can be misleading, they measured it with a single constant freq, but I'm quite sure that at different freqs (or pulse widths) the delay is different. (RF modulation freq is only 700 MHz, that's the source of my doubts.) I think this is the relevant specification:
"Precise timing (typical)
1.5 ns pulse width distortion"
But try it in a simple circuit! Maybe I'm wrong.
