Bitperfect means the same information.

Different volume means different information, how could a different
volume contain the same information, after all, ALL audio information
is only volume information (at different frequencies).
Well.. If the 16 bit sample is bumped
Not losing resolution isn't the same as bit perfect reproduction. Dts
information for example will get lost

Bit perfect is only at 100%.
What you are referring to is the effective resolution. Since the DAC
has 24 bits the 16 bits can be attenuated a fair amount without loosing
effective resolution. But its NOT bit perfect. The bits are being
changed, but you are not losing dynamic range of the
Yes the digital spdif is bit perfect until you are at 16 bits.
And the digital volume works with 24bit resolution.
So 6dB per bit gives you -48dB before the bits runs out .
(of course the increments are smaller than 6dB )
I have no idea what it represents is these 100 squeezevolume units ?
That
Was wondering if the Touch was bitperfect at less than 100% volume on
16/44.1?
And if so, to what decreased volume would it be?

The touch is bitperfect at 100% volume.
Search these forums for digital attenuation as to opinions on the use
of less than 100% volume, when using the analog outputs. It makes for
interesting reading.
If you are using the touch as a digital transport, use 100% volume,
then what you get out is
