Do you plan at some point to tell us something we don't know?I never said that the measurements say "nothing" about the quality of the sound. I said the opposite. First on my list to consider, THE MOST IMPORTANT THING FOR ME TO LOOK AT is Amir's review. That should be pretty clear to understand and I really don't get the confusion. Maybe it's because you and others "Prefer not to understand".
I also did NOT say that that science or measurements are the only thing to consider. Humans are affected by other criteria as well. Their perception of a product CAN be swayed by color or size or shape or price etc... To many people a higher priced unit MUST be better quality parts and render a better sound. Many will say...a $10,000 dac is certainly better sound than a $200 dac. I know... Amir has proven this is not true many times but you can't deny this bias exists.
The food industry also knows this bias very well. The 'science' of flavor works visual bias (red dye makes drinks taste more like cherry and so on). They use this to their advantage to sell more product but it also DOES make the drink more appealing, taste better and MORE EJOYABLE to most people even though it's fake!
Some people like products being pinned as 'snake oil'. To them the sound is better so it's a better product for them.! So what if they're happy with it? I see NO harm done if the customer is pleased with the product.
No one cares what your* preference is. The only issue arises is when you make fact claims about the product, based simply on sighted preference.
Unless properly qualified with an acknowledgement of the role of bias, even saying that A 'sounds better' than B is a fact claim -- it asserts that A and B produce sound that is different to an audible degree. And yes, that means the difference must be measurable, and of a magnitude above human thresholds of hearing.
