Steve,
they must have fixed the PN on the 3000 (or with a SW update), I checked my 3000 and the PN is perfectly flat.

Was the the headroom of the unit a big issue? As any professional sound device, the unit seems to clip the signal if positive EQ/channel gain is applied and a 0dBFS signal is recorded.
Actually on my unit a 0dBFS signal (internally generated I must admit) clips with channel level higher than -2dB if memory serves.
I've seen SDDS units which looked like Christmas trees when a loud scene was played back.
I was told that Dolby units were designed "idiotproof" and the USL have a selectable headroom (default is 26dB if I remember correctly which allows for the signal headroom and 6dB of EQ. There is also a 32dB which allows for +12dB EQ, 31 bands and shelves.)
