Tomcy6...to be honest...yes, I believe I can.
A few years ago, I went to an audio store to hear a particular Integrated amplifier on a pair of speakers that I'm very familiar with.
About 30 seconds into the audition, I asked:
"Are you using Audioquest speaker wires and or interconnects?"
The salesman was floored, as he knew I couldn't/hadn't seen the cables or interconnects.
Speaker cables and interconnects can, and sometimes do, offer very subtle changes, nuances to or FROM the sound.
Generally, at least for me, errors of commission are easier to quantify than errors of simple omission-I suppose this would fall under the topic of 'It's not what's right, but what's wrong', that creates dissatisfaction in an audio system.
The degree to which I can/do identify differences is fairly constant...the variable nature of cables, again, depending on their sonic character and the aforementioned omission/commission characteristics would be the keys to my ability to hear it.
Generally, longer sessions make those evaluations easier for me...as I do NOT grow accustomed to the sound...the longer I hear it incorrectly, the more I dislike it.
Blind tests, again, to me, are easy...I grew to become good at it, but it took many months/years of losing that 'angst' most people seem to experience when 'staged' with such tests/comparisons.
I hope this makes sense...great question.
