Please excuse me if I'm mistaking what you are asking, but as far as I can tell this unit includes an analog headphone-out jack, which as far as analog audio goes, should be just about equal in quality to dedicated RCA jacks, and in fact you can pass audio from this to a stereo's RCA input using a ~$5 cable from Wal-Mart or Target (which I do pretty often with my current rockboxed iRiver). Or is this not what you meant?
coacharnold:
Well .... not to sound like an audio snob ... but there is a HUGE difference between a 4 dollar cable from wall mart and a set of decent RCA interconnects ( not the least price ... I have a pair of interconnects that I could trade for a new computer) .... in fact this is one of the areas that DAPs lag behind serious high grade audio ... we spent a lot of time and effort developing flac and great digital DAP audio but we are limited to the weak links in the signal chain ..... as I see it here's the weak links .....
the D to A converter in the player itself ... the electronics after the D to A converter ... the headphone plug ..... and the cables after the headphone plug ..... this of course if you are using your DAP to run through an audio system as opposed to a set of good headphones.... even with expensive headphones .... the weak link is the cable and the plug and the output plug and D to A converter ....on the DAP
These are limitations .... even the best DAPs lack at the end of the signal chain ....
if your someone who has sent a lot of time, worry, and money developing home audio .. it's almost not even worth switching to digital audio ..... ( this is why a lot of us use Rock box in the first place .... so we don't have to use lossy formats like Mp3) .... I have been waiting for a project like this one for a long time .... the possibilities that this community has raised with this new Open Audio player are for far greater than what Apple of the rest of the digital audio universe has offered us .....
I know I'm asking for the Moon here ... but I'm seriously excited by the possibilities of this open sourced player ......
thoughts??

The iRiver H100 has a digital optical output, so you can attach it to whatever you like and use the DAC and analog electronics in that, letting you choose entirely what sort of signal quality issues to introduce (or not) by what hardware you attach it to.
Digital output is something that has been recommended many times for an 'open' player to run Rockbox on, but there will always be limitations on how many ideas can be included.
coacharnold:
I think I knew about the digital output in the h100 --- it's something that Iriver was way ahead of the game with .... I wish they still made that player .... I'm glad to hear that some sort of hi fidelity output has at least been talked about .....
thank you for responding ... you folks are doing an incredible job with this project ... please don't think that I'm complaining .... I just found out that this project existed a week ago ...

If you want to help/discover/learn about this hardware and audio quality, try to buy it, use and hack ;-)
