Steve G has a point

The difference, potentially, is in the relative probabilities of those responses for each of the two situations.

When opined upon, the objective becomes the subjective. 

I saw the video and it was interesting.  That’s one of the reasons I get more from reviewers that share both measurements and listening impressions.  Erin’s Audio Corner and James at Audioholics are 2 good examples.  I agree with his comments about finding someone that has similar tastes or ways of looking at components to use as a reliable resource.  

I read that too and thought he made some great points. The one I liked best was about a speaker review. He simply said every piece of equipment that the original music  goes through affects the final result. From the stylus, the cartridge, wires, phono amp, preamp, amps, interconnects to power cords and speakers. Change any one component and it’s “different “.  Not to mention room acoustics. The music or signal is the only consistent thing, the processing is the challenge and a moving target. And then there those including my self that suffer from listening to music at way to much volume in our youth that has compromised our hearing.
