I would think 6dB would be in - its a psychoacostic effect, humans cant
detect the harmonic distortion from clipping at very short durations (< 1
ms or so I think).

In any case it would definatly be an option, the extra headroom isn't
always desirable, and it might be audible under certian circumstances.
