In Reply to: RE: Cable shootout.. posted by tomservo on June 21, 2014 at 19:29:11:
I nulled out two of the cables using the WAV files. The null was at -75 dB relative to the original music. By cranking up the volume by +26 dB and listening carefully I could hear the difference, which sounded like quiet music in the background, not noise or distortion.
I would have to see an indication of repeatability (multiple tests with a given cable, with and without disconnecting and reconnecting and done in a random order by cable) before I would attribute any differences to the cables themselves and not some other aspect of the experiment. It's all too easy to conduct experiments that one believes to be measuring one thing only to discover one was actually measuring something else.
To put things in perspective (not sure that's quite the word) I've seen a number of audiophiles report big differences in files that differed only in the low order bit of a 24 bit format and other files that were identical except for a few hundred extra leading zero samples at the start. In one case a file that differed only at -138 dB was described as "completely trashed".
