He makes his case well, and if he has thought it through that carefully, and lived up to it informally all the years he's been in business, he can probably do even better with the relationship codified. Journalistic ethics have never been a problem at 6Moons IMO. Credibility is. It is exemplified by the photos in this article. 6Moons is a purely subjective site. They won't measure. But, evidently, they won't listen in decent rooms either. It's one thing to listen in a "normal" domestic space with rugs and over-stuffed furniture and lots of natural diffusers. It's not an ideal thing, but it's what most listeners get and, therefore, a legitimate choice. But look at the rooms in those pictures. Look at the speaker placements. Half of them are acoustic nightmares. They are listening in those rooms and writing purely subjective reviews based on that listening. In some of those cases, they don't really have any idea what they're listening to. Half the time I stop by that site and read a review, its credibility is destroyed by the pictures of the listening space, and the credibility of the writing staff is destroyed by the fact that they evidently don't know any better. I'm not demanding room treatments, even. Just decent speaker placement and a lack of obviously noisy, reflective, parallel surfaces unacceptably close to the speakers would be a good start. I wouldn't set up mics and record guitar and voice in those rooms. Review hifi at realistic volume? Not responsibly.
