I'm not an audiophile and I'm old (can't hear anything above 12-15kHz).
I don't believe in most of the audiophile talk but I believe in science.
Just one story about 10 years old...
I read a gazillion times that 128kbps MP3s are really close to the original and nobody
(statistically speaking) can hear the difference between a 256kbps stereo track and its WAV original.
And i believed that because I can't hear the difference.
Until I met a person that can.
In 9 cases out of 10 he was able to do what I thought was utterly impossible: pick 192/256 kbps MP3s from WAV.
On relatively average equipment.
Bottom line: I still can't hear it.
But I think twice before claiming nobody ever will...
BTW, HDMI as a standard is such a mess, it's not even funny...
Diogen.
Agree entirely on the standard. If you recall, I had a pretty intense argument a couple of years ago on the subject where I stated that the HDMI alliance was more concerned about manufacturers using the logo properly and paying the royalties than they were in performance testing. When I read the certification specs, they were all about marketing and not about performance.
I agree on the fact that some people can tell subtle differences. In this case though, I believe those differences would show up in how well the player generated consistent clocks and how well the receiver did the time base corrrection. I really don't think the cable could color the signal, and I'd love to see any well designed test that could show a double blind difference on a reasonable sample size and explain why. I just don't think it could be the cable.
Also, with the guy that could do it... Were the number of bits in the encoding DAC consistent? Were both signals generated from the same analog source? Were the #of bits in the decoding DAC the same? If not on any of these, you would hear a difference in the number of distinct steps and that could show up as lower frequency harmonics. I think it would be very difficult to design a fair test there.
BTW, I'm just as old (61) and I drop off quickly at about 11kHz.
