Subject: RE: Archos firmware sound vs Rockbox

Thanks for your replys.

Your absolutely right headphones can make a huge difference to how
something sounds. The ety's I mainly use are very sensitive and neutral
so they should be good with both firmwares. Even though there may be a
difference in sound between the two firmwares it is not necessarily
large (I still enjoy listening via the rockbox firmware). It is also
hard to know what inbuilt sound adjustments have been made beyond the
setting we can change. I suppose what would be great is if the rockbox
community continues to try and pull the best sound out of the archos.
That’s all you can do really.

Mark

Hi,

this may depend on the equipment you use (type of earphones or
resistance
of the line in of the amplifier).
I noticed, that there is a different behaviour between rockbox and
archos
firmware depending on the headphones you use.

If I use my usual headphones (a closed system sony earphone) the sound
is
great with both firmwares. However if I use my big headphones which I
usually use at my stereo system the sound is distorted if I use rockbox,
but
is much better with the archos firmware. Or what is more correct:
auditible
distortion starts at a lower volume with rockbox than with archos
firmware.
I also noticed this difference on some line inputs to car amplifiers,
where
rockbox does sound distorted.
Probably the larger headphone draws more power and the archos firmware
is
better able to deal with this?
So my finding is, that one should use headphones which have a high
efficiency (neodym magnet). I use a Sony MDR-EX70LP.

André
