I think this, quoted from above, sums up most of it:
"I think that audiotroy is talking about two separate topics here:
1) Threads that go off the rail, off topic what the OP is asking about.
2) Whether technical jargon should be discussed in the forums.
Forgive me if I misread you, as I'm not exactly sure which thread you are referring to, but that is what it looks like to me."
Beyond that - and not defending arguments, flame wars, or pedantic back and forth, technical details result in the sound. Often, an observation that "A sounds great" is really only true in a specific context - due to technical stuff :-)
So if we understand what is REALLY going on, we can have far better understanding of what will result in great sound.
That said, finding the root cause, while holding all the other factors constant is really, really hard.
