When I listened to the tracks first on the crappy usb headphones, the first vocal track had some nasty distortion on the right channel at the end of the track which seemed first listen to be worse on some tracks than others, but then I started to not be able to tell
I've just done a little bit of DiffMaker type of investigation, and there's a couple of things of interest which may or may not help people: in the DA/AD loop there's a little bit of phase shift at the low end; and, the right channel has more distortion than the left in the midrange, not dramatically so, but definitely visible ...
Hmmm, it seems that my first impressions are probably the ones I should take most note of!!

This may give an indication why ASIO Audio Interface - Audacity Wiki Not sure if you have the tools to compile audacity yourself?

Well it looks like this test has fizzled out. I've gotten only 4 people to guess which material is which - three of whom correctly picked the original file. Been deadly silent for days. Are the rest of you cowards, deaf, or just not interested?
Haven't had time...
I suspect you've also put off a few people by posting other's results. I would have kept quiet about everything until the final reveal.
Tried following up Pano's comment on comparing copper with other materials - so, how about steel wool?
Scary stuff ... the nulling between copper and steel wool is impressively good, can get as good as -60dB at the peak of the original waveform, if fine tuning of amplitudes is used. If the difference file is amplified 50dB, then every area where there is a significant deviation can be seen to be merely an echo of the original waveform -- this implies that subtle timing wobbles are more of an issue, at the visual level, than other things ...

The tracks should be trimmed only at the beginning and the end, nothing in between. But there could be a mistake somewhere.
Diff Maker often reports a sample rate drift for these files, I doubt it's a real drift. I think what happens is glitches that cause offsets, and Diff Maker see those as drift. I've been trying to fix that. If I could get both playback and record thru ASIO a lot of those glitches should go away.

I'm not sure but I think Malcolm Hawksford said that thinner cables should be used:from a physics point of view I can see the logic in going for thinner cables over thicker.

That article appears to make at least two mistakes, which may be sufficient to render its conclusions invalid:
1. failure to distinguish between phase and group velocity - his speed calculations look suspiciously low,
2. failure to recognise that the 'energy storage' is simply internal inductance.
Hawksford seems to have a knack for writing articles which look impressive and 'scientific' yet his arguments often don't hold water.

For me, it's too close to call on my PC-speakers (which are quite good), and I am too busy with other stuff to move the test to the large system.
At any rate, the differences between the uncompressed files appears smaller than between these files and the MP3's that where posted in the beginning of this thread; between FLAC and MP3 I could differentiate with some measure of confidence.
Quite remarkeable all this.

I recently immersed my interconnects in hydrofluoric acid (along with some rocks I was trying to dissolve the quartz off of). After a few minutes, the sound took on an ethereal quality, and ultimately the sound of the interconnects vanished completely, and the music followed suit.
However, I still heard the music in my head.
