Pardon me, but you were the one who said this:
--- Quote ---anyway that post is getting on for being nearly a year old so something could have changed or has no development happened on RockBox for nearly a year ::)
--- End quote ---
The implication that if the one feature that you are interested in has not changed then this means that no development has taken place at all seems a bit like trolling to me. The "eye roll" only accentuates this perception. Honestly, it would be easy for the people who have worked hard on Rockbox during this time to take offense about that. However, my comment was not intended to be overly harsh. I only wanted to draw your attention to the fact that whether or not this feature has changed and whether or not Rockbox has undergone development are two distinct things.

Well I come here as a new user asking a question that is of interest and all I basically get told is that I'm an idiot for not finding the answer myself. I did not expect anybody to start resarching documentation for me but hoped that perhaps somebody who actually knew the answer (which it does not seem that either of you two do) would read the question and come with a polite answer.
Also I'm not in posesion of measuring equipment that would let me measure what the specs of the signal coming out of the optical output on an iRiver is (and I expect not many have that) and neither do I have a SACD player or any other device that delivers anything better than CD quality so I don't know what to expect and therefore cant compare the sound as I also dont have those specific recordings in ordinary cd version.
I have now poked around a bit more and read the spec sheat for the Phillips ADC/DAC chip that is in the H1XX units and it seems to be able to handle 24/96 (but not 24/192) so it actually seems that it would be a usefull thing at least in these units.

Getting angry when people don't know things you also do not know seems like a reasonable thing to do.

Yes, that was his point. If you can't tell the difference (which apparently you cannot), then it doesn't matter. Unless I'm missing something, you just answered your own question?

Not following you on that one. Why do people who also don't know the answer have to tell me I'm an idiot for asking instead of just finding out for my self, they could just keep quiet ???

I never said that I couldn't tell the difference, I don't know if I can tell the difference as I have never heard a hires signal before and am not in possion of a device that could play me such a signal, that is why I was interested in whether the RockBoxed iRiver COULD deliver such a signal so I could find out for myself. Say I play the same tune as a 16/44 file and a 24/192 file and don't hear a difference, does that mean that I can't hear the difference or that the unit cant play the full resolution of the 24/192 file and therefore are playing both as 16/44 ?
Chronon:
Honestly, you would do yourself a big favor to find a way to run an ABX test properly since even moderate bitrate lossy files are transparent for many people. I have not been able to find evidence of people who can reliably distinguish 24/96 audio from 16/44 but have found accounts of studies that unanimously show the converse -- indistinguishability.
Edit: Pointing out that you can answer this for yourself is good advice. And I don't see where Llorean ever called you an idiot. He just pointed out that you could probably answer this for yourselves much faster by testing than waiting around for an answer. Many computers have a digital input these days. This would give you a way to characterize the data stream coming from the digital line out. I also have a digital TOSlink input on my stereo receiver that accepts 24/192. Of course, we don't know what equipment you have, but I still think it's good general advice to point out that you can probably find a way to test this yourself.
