Rrrightt!
That's a kind of revelation to me
 ::) ::)
'cause I thought that the audio going through the headphone output undergoes an additional step of amplification, potentially coloring the sound or adding noise.
I read somewhere:
"The line out is a line level signal, meaning it doesn't go through the iPods headphone amp circuitry.
If you are going to another source you will get better results with the line level"
????
Also I found this NOT to be true:
"...you basically have control over the volume of a headphone plug, but a line out is at a constant volume" : well, how come I can change the volume in line out?

torne:
If you don't know what precut is then you probably shouldn't be worrying about the impact of an amplifier on the sound.. ;)

soap suggested you use line out, or headphone output at 0dB; you are already using line out, so that's fine. The difference between the two is not something you will notice.

I already explained to you what Rockbox does with the volume control: in order to support playing audio very quietly (quieter than the lowest setting the hardware supports, but not actually muted) Rockbox scales the digital audio's amplitude down in software if you decrease the volume extremely far. Since this is done in the digital domain it also affects line out, but if you were using the headphone output you would find the volume at those levels is already so quiet as to be basically inaudible ;)

h.finn:
ok
point taken

 :'(
I'll study all the info a bit
 :)

P.S.: just a little point: having a "good ear" for music, doesn't necessarily mean knowing the technical details, right?
 ;)

No, but the sound quality differences between minor variations in the analogue path, on a portable MP3 player, are something that generally only "audiophiles" would care about; they're not something that people actually *hear* unless the hardware is crappy. There's a difference between having a good ear for sound and being concerned about entirely hypothetical differences ;)
