Observing comments on the quality of the sound,
compared to the native Archos software, I have the
following observation:

Indeed the sound at the "standard settings" sound a
little muffled and the bass has a poor definition.
I have my settings at:
volume: 70 archos: 3rd notch
bass: +6 archos: +2 notches
treble: +3 archos: +2 notches
loudness: 6 archos: middle
bass boost: +30% archos: +2 notches

Starting experimenting with the Channel setting
(because of a poorly recorded song), I noticed that
the "Stereo Narrow" setting gives a better defined sound
than the standard "Stereo".
In Narrow mode, the sound is very comparable to when
running the Archos software. Since the DAC is
responsible for the sound, could it be that
Archos "Stereo" equals RockBox "Narrow Stereo"? and
that actually "Stereo" as defined in RockBox would be
regarded "Wide" ? Is this a bug, or interpretation?
(not knowing how granular you can control the DAC's
settings in this respect).


Keep up the good work. You gave the Archos a new

All I can say is that Rockbox has 100% stereo separation in
the normal Stereo mode. This is programmed according to the
MAS data sheet. However, I am planning to introduce fine
tuning of the stereo separation in the future, allowing the
user full control over the channel mix.
