OK, so if you can't hear 12kHz cutoff (which can be understandable since adult might not have great hearing on the upper treble region due to natural aging), and how's that going to affect you giving S2 a great review or not? How is that going to affect the reader of your review who trust your review? I am not saying I want to see perfect measurement on every audio devices, I just saying this is a low level mistake that should have been ruled out during the debugging process by a simple measurement using an audio analyzer, but the fact is it didn't. What kind of audio manufacturer should be allowed not to debug its device before release? What kind of audio manufacturer who advertises its EQ ability but forgot to leave 6dB of headroom to avoid clipping, which is a common knowledge in the industry BTW? Again, I am not asking for perfection, I am just saying that if you want to publish output power on 10% THD+N (which other publish under 1%), at least you should have the ball to list down the detail. I am asking manufacturer to do some basic homework before releasing their devices, so they don't release products with obvious issue. WE ARE HUMAN, so I understand some of these issue might not be very audible or immediately obvious to our ears, at least not to everyone. But that's no excuse for manufacturer to skip basic measurement and let simple mistake passes by, perhaps hoping no one will hear it? I don't believe in either 'measuring over hearing' or 'hearing over measurement' - I believe they should compliment each other, and that's how we can keep ourselves honest in a hobby that is both important in subjective and objective experience at the same time.
