Thank You for your continued support and contributions!
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
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.

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?
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.
I give up. Some admin please delete my user and posts and forget you ever heard about me and you all go back into your smug little selfasured world where outside idiots really aren't wanted. Over and OUT, OUT, OUT ...
Rockbox plays back files of higher bit depth and higher sample rates than 16 bits and 44100 Hz just fine right now, but not with full quality. Here is what happens:Bit depth: Rockbox will decode all formats to as high a bit depth as possible for both lossy and lossless formats. All internal processing is also done at 32 bits bit depth. However, all current targets truncate to 16 bits at the output. This can be fixed if someone cares enough about it to do some programming, but the DACs in current targets really aren't good enough for this to make much sense.Sample rate: Rockbox will decode higher sample rate files (like 96 kHz) just fine, but resamples to 44100 at the output, so some quality is lost (especially considering the extremely crappy resampler we use). Again, someone needs to care enough to do some programming to fix this, and it makes more sense to fix this problem than the bit depth problem.
