I don't know why measurements were even brought up if it doesn't have anything to do with opinion, then why bring it up?
This is a never ending tactic - conflate comments in support of measurements as another tool to evaluate audio gear with their sole use in evaluating audio gear.
I have said repeatedly that measurements are useful to me in evaluating products as far as engineering, performance, suitability in my system vis a vis other components, etc. are concerned. I have also said repeatedly that the ultimate arbiter is how the equipment sounds in my system in my room. Yet over and over I hear the comments about how "I learned 50 years ago that measurements have nothing to do with the sound", "measurements are useless in determining how something will sounds", "go to ASR", blah blah blah. I can not help but conclude that several posters here have a reading comprehension deficiency and/or a fear and lack of understanding of things numerical and technical.
By the way, the designer of this class d amp surely used measurements to develop and engineer this amp. He also, based on comments he has made elsewhere, believes that measurements CAN indicate how an amp may sound, contrary to all those here who claim otherwise. Measurements and science play a crucial role in the design and development of audio products. They can be, if understood and properly interpreted, a very useful tool. BUT NOT THE ONLY TOOL.
