The hardware in the transporter can do 192 but not 176 (its an issue of
crystal frequencies). The Touch can do both 176 and 192.

The Touch would be a better candidate due to the faster processor. Even
then I would only even attemp it in wired mode.

The driver code3 for the Touch is publically available, I've taken a
look at what it would take to add 176 and 192. Its a moderate amount of
work. Its not just adding another number to a list of frequencies, every
sample rate has to configure the DAC chip and clock muxes etc, and setup
the appropriate parameters for buffers etc. Its not really hard but its
not trivial either.

The design team has not shown ANY interest in doing this, and I don't
blame them, there is LOT more important stuff for them to be focusing
on.

Since the source IS publically available you can edit it yourself if
you are into writing ALSA drivers. I could do it but I don't have
anywhere enough time at this point. Then there is no guarantee that
logitech would accept it and include it in the firmware.
