More thoughts:
I agree with a poster that mentioned that product development is mostly "trial and error." The "Hey, lets try THIS and see what happens" may be a common occurrence. So, it sounds better. Now what? Then the task of objective assignment of cause and effect takes place.
I can see several scenarios here when significant a sonic benefit is achieved:
1) They nailed it!! The SQ is there, they are highly confident in their engineering, the science aligns with empirical data and scientifiy community, and there’s a strong concensus in the technical community that something valid just happened. The item get great reviews and glowing technical writeups.
2) They have a pretty good idea what just happened from an engineering perspective, and do their best to describe it, but understand there may be other variables. The possibility also exists that some of their assignment of the "whys" are not correct. White papers are presented, they are met with some pushback. Critics may listen, compare and comment.
3) It sounds awesome, they have no idea why, and are left providing their "best guess" of why it sounds like it sounds. The scientific community’s propellers spin so fast their collegues have grab hold of them to keep them going airborn. The product is widely adopted, gets favorable reviews from those willing to listen. The item is shunned, ridiculed, and mocked by those that can’t attach the correct metric to the outcome. Or, reject the premise of "better sound" altogether.
Then, there’s a 4th possibility:
- They nailed it! Wonderful sonic improvements across the board. The science is spot on, yet does not agree with some in the scientific community whose education, training and experiences differ. We find ourselves here quite often, in my opinion, where gaps in knowledge bases are unacknowledged.
It brings up the question: If the wrong ’why’ is assigned, does it justifiably disqualify the premise that the item has real world sonic benefits? Or, does it just make life more difficult for those producing and marketing the item?
Someone, for example, introduces a brilliant speaker with highs so delicate you’re terrified to move your head from side to side in fear you’re going to break something. Their explanation of the ’why’ is: "Compared to the lower-priced models in our line, we’ve found that the symphathetic resonances of genuine zebrawood veneers produce more musically satisfying even order harmonics compared to simulated vinyl materials." Giving the above "technical explanation", should we disqualify the item? Or, just rough up the technical writer a bit, and give them a listen? The correct technical explanation is buried deep in there -- somewhere. They just haven’t found and/or properly communicated it. They could be sitting on a breakthrough product.
