I have trouble
with almost anything I change sounding different. I've recently had an
identical mp3 file on my synology NAS box and on a data stick. Both of
these files are accessible from my blu-ray player which outputs the data
as spdif to my AV8. They sound quite different. Thinking this must be
something to do with the way the BD is retrieving the data I thought try
another nas. So I downloaded some server software for a PC and got my PC
'doing a NAS' with the same file. Different again. The synology as far as
I know is serving in the same way as the PC UPNP? Something like that. The
Synology has quite a bit more bass than either of the other two. Not
better but different and I don't know why.

Clearly my understanding of how the above works is incorrect as it cannot
explain what I hear. Not only is the only difference totally in the
digital domain but its even before being decrypted from mp3. Nor can I
think of the slightest reason why my brain would invent such a difference,
I was quite shocked when I noticed it.

If you can determine the difference in a controlled double blind test
then I'll eat my hat.
