Sure, nowadays there are so many reviewers and review Web sites that there is an unevenness in coverage. Online influencers and youtube reviewers typically have no editors and thus no editorial or publishing guidelines -- I cannot speak to those. However, I find that you indiscriminately paint with too broad a brush and provide no examples to support what you say. Rather than offer suggestions to make things different you are soley negative.
As far as personal ties go, I interact with manufacturers in an effort to understand their product in order to insure what I write is technically correct and, if fortunate, to gather information not available elsewhere. Manufacturers get no say in sonic descriptions. I've written reviews of the Atma-Sphere products that you carry -- tell me if and how they are compromised. Unless no one in Indonesia reads audio review, as a dealer you receive benefit from them.
As far as financial incentives go, a reviewer receives payment for his review in order for a publisher to own the review product -- payment amounts are a pittance relative to the work done. Reviewers may receive industry accommodation pricing just as you receive as a dealer. Under publication that practice is heavily regulated and not hidden.
