Yep - the spectrum analyser showed a trace at around -93dB across all
bands. Is this meaningful? I guess it may be higher for the mic
preamps.
With further testing, I think I can detect a similar change in gain
effect from what Robin reported - I seem to be getting between -13.0
and -13.6 db at the lowest end of the spectrum for the snippet that is
being played back. Seems a bit random where it comes though. I think
they are analogue pots, so maybe this might account for this
variance?? - anyway, I think it is too subtle to notice in normal use.

noise when gain was set to just below clipping
(going by the red
warning LED on the device) was < -90dB (according to the spectrum
analyser on audacity).
Do you mean the spectrum analyser showed a trace at -90 dB ?
