Some notes on 96khz:

I tried working exclusively with 96Khz for about a month. The dynamic
range is so extreme that the faintest of sounds are picked up.
"Silence" no longer exists. ANYWHERE. Ladspa plugins like gates don't
go below -70db, and they need to. A plus was I felt free to sell all
my outboard compressors. My analog synths sounded fatter, voice more
robust, but at least some of that was the result of turning my knobs
down from "11" to give me 10DB or more of headroom. (I'd fallen into a
bad habit)

The 96Khz Bardsdown bosendorfer does sound awesome at 96khz (even
though linuxsampler only does 16 bits, not 24). No background noises.
I do use 96khz when I'm just playing piano, no vocals.

I went nuts during this period quieting my studio, cutting various
noise sources by about 8 db overall. (now saving up for  a sound
booth) I was still unsatisfied with listening directly to the 96KB
recorded results - I could hear leaves in trees blowing outside (I
don't exaggerate)... but the 44khz mixdowns were nice, all that extra
stuff dropped out. I went back to straight 44khz/24 bit afterwards and
although the sound seems "deader" I don't hear all that extra stuff
all the time, and the savings in disk space and mixdown time are worth
it.

Note: I have a good ear (can hear up to 22khz in one ear - compensates
for the other which doesn't go above 4k)

So having hires audio is good for debugging your studio, and pure
96khz sound sources, but not so hot for development or analog work.

The primary reason I remain interested in using it is to encode down
higher quality surround.
192Khz strikes me as complete overkill, except perhaps in that instance.
