i am not talking all or mostly about reviewers. Most groups have hundreds even thousands of users, and only a handful of reviewers, who participate to share listening impressions of different gear. Most all of the buying is by members not reviewers for the latter get samples sent to them gratis.I am talking buyers not reviewers. The reviewers you reference basically do not pay much or any attention to measurements. Like most buyers, they say they like the sound. Either they do not hear or perceive distortion at that level (quite possible), enjoy the effect of distortion (possible) or don't listen critically. Also, I have yet to see an audio reviewer post his or her latest hearing test. But most people's hearing is not flat, and many reviewers are middle aged or older. Most people are not adept at, or able to hear, some types of distortion until it is rather high. And no doubt many listen to their Hip DAC on crappy ear buds or headphones listening to lossy recordings. A few like those on this forum demand more from a manufacturer. Thankfully some supply that.
