st2lemans,

Ah that's interesting and makes sense. So reducing the loudness by half
cuts 1.66 bits off the resolution. I knew there might be a problem with
my calcualation- didn't know it's as big as that! 

I see that now at:  

http://en.wikipedia.org/wiki/Audio_bit_depth 

It looks like you know a lot about it. Can you confim that squeezebox
works in the digital domain and then passes this through the DAC? What
about my average computer sound card?

Another question: 

From: http://wiki.slimdevices.com/index.cgi?ConnectToPowerAmp

"the output line levels vary somewhat by type of connection and between
devices. This is typical of source devices... This difference is one of
the things the preamp controls"

So how can the preamp control this? I thought the line in was pure
analogue... If I play a 1kHz tone at half volume down the 'line in' how
can it tell that this input uses a different maximum level from some
other? That makes no sense to me- unless they mean the preamp has phono
and cd inputs which are hardcoded differently.
