If you're going to dismiss the lack of objective measurements, then all that's left is your subjective impressions, and the only way to verify that those aren't just you making stuff up is for your impressions to pass a basic test of validity.
If you dismiss all forms of testing, then you're not being scientific. (The acronym AVS stands for Audio Visual Science.) It's okay to be a mystic, but don't expect to be taken seriously.
The human capacity for self-delusion is almost limitless. For thousands of years, we wandered around in a fog thinking things like "bigger objects fall faster", because we hadn't clued into the idea yet of testing hypotheses. People still think eyewitness testimony is the gold standard (they "know" what they "saw" with their own eyes), when it turns out to be remarkably unreliable, as shown by objective, scientific, DNA testing (http://en.wikipedia.org/wiki/Eyewitness_identification
Now that we know about testability, we live in a world of seeming miracles, courtesy of the scientific method.
It's not really true that everyone has a right to their opinion. For example, a physician who still practiced phrenology because, in his opinion, it was beneficial would be driven out of the profession. Not all opinions have equal value. Some are complete hogwash. It's important to know how to distinguish fact from fiction.
We just got done with an election in which an entire political class deluded itself into not believing data from scientific polling, because their "pundits" were convinced of systemic bias. You know how well that worked out for them.
Audiophiles can't tell the difference between coathangers and Monster Cable in a single-blind test. That should make audiophiles step back and go whoa, what was I thinking? Instead, they redouble their efforts.
Someone will probably object that this is drifting off topic, but if you review the past couple hundred posts, a significant percentage of them involve unsubstantiated claims about unmeasured (and probably unmeasurable) characteristics of the Oppo 105 and various other components.
