"In computing terms, I call that a bug, not a feature."
Most would call that innovation or progress: The notion that I can do it better.
"I wasn't actually arguing that point. I just picked the "bit perfect" one as being at least somewhat topical. Are there any audiophile features/tweeks/"differences" that, in your view, make no difference, or do you think absolutely everything matters? "
It does not matter because i granted your premise.
That is too comprehensive a question to answer here. I will venture that over my audio journey things that i thought did not matter, turned out to make a difference.
"Anyway, let's pick something that really isn't going to make a difference - magic crystals, or a plastic insert between your power plug and the wall socket. My point is that according to your logic, you might still hear a difference - depending on the brand and manufacturer of the crystals or insert."
"My logic?"
For any claim to be credible it has to be effective. Companies that have a history of doing just that deserve consideration when they claim they have perfected extraordinary products. Or improved on existing ones.
