Ok - so peterw's change
(http://forums.slimdevices.com/showthread.php?t=77837) 'just' locks the
volume at 100%.
I do accept that running at 100% volume (and adjusting the volume via
your amp) will improve playback quality (as the original bits are sent
to your amp).

What I don't accept is that you are telling people that just putting
the volume to 100% is not enough but your mod again will improve stuff
because Logitech is lying to us.

Luckily this time this is proved easily: at the corresponding code line
you are changing there is a log output right before. So anyone having
enabled logging can test for himself: 

In SqueezePlay: 
Settings->Advanced->Log->audio.decode.

One just has to set it to Debug - then the following lines will appear
in the log when I change the volume to 100%:

Code:

20110122 20:37:31.116 DEBUG  audio.decode - Playback.lua:871 gainL, 
gainR: 65536 65536
  
--------------------


So SqueezePlay (the firmware of the Touch) indeed uses the maximum
possible value for it's internal gain setting when you set it to 100%.

'65536' is exactly the same value that is used in your mod.

So while it's nice to have a mod that fixes the volume at 100% - and
while it's nice to give people the hint, that they should prefer the
volume control of their amp (and set the Touch to 100%) all other of
your claim are pure nonsense.
One can achieve the same results with following just the beginning of
your blog:

> 2. Play a track. Slowly drive your Touch VC towards
> 100%  while adjusting your external control to 
> an acceptable level.
