Thanks for your feedback. I am always looking for ways to improve these reviews. Per your point about the graphs, I tried to make them as intuitive as possible. We do have links to articles that explain their meaning below every graph that isn't a flat frequency response or impedance/phase response. Compared to spin-o-rama, I would have guessed my graphs are much more intuitive since they are just different ways of looking at amplitude response per angle. In comparison, spin-o-rama needs careful explanation, even for audio industry veterans.
As for handing out negative reviews, I need to get sent products that provide more of a negative experience than a positive one. Even for products I reviewed that I am not crazy about, they still have their positives and use cases where they work well in. Most manufacturers know better than to send me something that is just junk, and I don't accept products in for review that I think will be nad from the get-go. Nonetheless, few products sent to me are perfect, and I like to think I do shed light on their flaws. For example, this review of the Ultra Evolution Pinnacles is probably the most critical review of this particular speaker out there so far, even though I did quite like the product.
