I think there is a lot of evidence that an individual's hearing, home setup, ambient noise, and tolerance for the problem are just as important, if not more so, than individual set variabilty to determine whether someone believes the buzzing is a problem.
I realize that you believe the set variability is the reason because you have come to possess a set which seems improved over your first one. And there are other reports of similar circumstances as the population of people owning two Kuros increases.
My experience is having three sets in front of me at one time all with the same level of buzzing. Quite a different experience.
But there are many more reports of people continuing to be dissatisfied on subsequent sets if they are unhappy on the first one. Can you fish through several returns and find one? Maybe, but the odds aren't on your side. So if you are unhappy, move on.
People want to believe this is some quality control issue that needs to be fixed rather than a consequence of design features (no second glass, firing sequence) that are responsible for the beautiful picture produced by the Kuro.
I was told by a Pio engineer that the buzzing problem could be improved if the firing sequence was changed but probably would have bad effects for the picture. Shudder to think that maybe those non-buzzers might be modified in some way.
How about adding the second piece of glass?
Would those be acceptable solutions?
Not for me because the I see the great picture 100% of the time and only hear a buzz 1% of the time with normal content.
I think every potential owner has to weigh whether the buzz level is acceptable. But if you find it unacceptable, its very likely that your individual tolerance level will find the next Kuro you hear unacceptable.
