Well, it wasn't my intention to start a thread about who's the more real-world guy: the one who is able to notice a difference or the one who lives happy and in peace with his 128k mp3 collection. But to answer your question: Obviously yes. And (I did another test yesterday) there's a mimic that inverts the signal a second time on the line-out channel.
That is, with recording via line-in and playing back via line-out you'll be fine because the signal is inverted twice. While data transfered via USB to the X5 plays back inverted and data recorded via line-in and transferd off the X5 via USB will lead to an inverted CD.

So my question to the programmers: Why not invert the record buffer just before writing data to disk and doing the same before feeding the DAC with playback data? Or would that cause too much overload?

Llorean:
Pardon my ignorance. What exactly is one supposed to be hearing different with an inverted audio stream? My understanding of sound was that it was amplitude and frequency that matters, and these remain the same with an inverted signal.

LuzifaHell:
*knock-knock* Anybody out there capable of answering a question instead of, first and foremost, doubting the reasons for putting it? Please?

Thank you in advance.

Llorean:
Surely if he's asserting change need be made, it is reasonable for one who doesn't understand to ask why?

And remember, we can see the logs in the forum so it's pretty obvious to us when you create a second account z-man. If you don't have an answer, just say it.

Oh yes, of course it is, and you'll find the explanation in the very beginning of this thread, I think. I just wanted to know if there are any programmers around, whom the question is ringing a bell with, and if they've got an answer -- and if so, which one, of course. :-) ).

P.S. OMG... no, I'm not Z-man. I'll give you my XING-profile via mail if you want me to. Plus explanation. Tis-tis-tis.
