 Therefore, I am thinking the line noise reduction at the speaker cable output should be audible, if the detection threshold in the Petri-Larmi AES study is valid. What do you think?

What do you think? I think you have a theory, now all you need to do is test that theory, the same way as Petri-Larmi. That's just what I said before, the difference should be clearly audible in ABX testing, since it's 00 times greater than what they detected in their testing. Now for the long winded excuse as to why ABX testing isn't suitable, even though you use it to arrive at your (unproven) conclusion. Rinse, repeat.
