Which is a classic case of "when doing abx, I cant tell the difference,
but when I know there is a change I can hear it".
The ABX results imply that for this listener/equipment/music, there is
no -real- difference of the waveforms hitting his eardrums.... but
there is apparently a perceptual difference when that vibration is
processed by the brain.
Again, note that this is the same listener, equipment and room.
Perhaps the music changed, or more likely, the listener's
built-in-audio-processor is interpolating data. (ie, his brain is
futzing with the data.)

And dismissing that the -exact- same listener knows that he didnt pass
an abx test (not even a double blind!) is far more foolhardy. Are you
saying his abx test was faulty for him? (It may or may not have had
different results with someone else, or different equipment, etc... but
then those did not change between the test and the real world...)
The most likely explanation is very simple: "expectations" and the
magical power of the brain to mess with our senses. That is the
-only- thing that explains the single-blind ABX test results.
You can debate all day about whether running 1000 random listeners in a
double-blind test is valid ("they are all deaf it seems, I hear
differences!" or whatever). But that is not the case here.
Implying that the decoding of FLAC changes the sound.. but only when
his friend is not running a blind test for him... is ... nonsense. I
don't recall reading of an RFID reader in the SB and the original post
didn't say that the friend had an RFID implant... so why would the SB
behavior change only when being observed?
This is not quantum mechanics. The uncertainty principle doesn't apply
or all of science is pointless.
(And, no, I don't think Ken is lying when he says it sounds different..
it quite likely does: the question is -why- it sounds different when the
only change made is that he knows the source format. That, again,
points to the brain being the reason for the change.)
