This may be true for some reviewers. But it is not true of Michael Fremer of Stereophile or Don Saltzman of The Absolute Sound or of Tim Aucremann or Danny Kaey of Positive Feedback or of Matej Isak of Mono and Stereo.
Sometimes you have to understand the sequence of the reviews and the evolution of their opinions and comments, and sometimes you have to read between the lines a bit, but these reviewers are intellectually honest.
Thank you Ron. I
very much appreciate inclusion in your list!
I was staying away from commenting in this thread. Being a reviewer for going on 16 years, now I'll chime in with my perspective. I held back mostly because I didn't think it appropriate to comment on the OP's title question: "What makes a good reviewer?" because it asks about a person, maybe a hypothetical person. I'm disinclined to talk about reviewer personalities, though I admit to not following that maxim one-hundred percent. I am pleased to see some of my fellow WBF denizens answer in the abstract, although it's natural to comment on real life examples.
"What makes a good reviewer?" Apart from whatever we each mean by "good",
a good reviewer is one who writes good reviews. There is no standardized list or set of industry guidelines covering the qualities of a good reviewer or a good review, although several comments here mention characteristics to which all of us (most) can agree.
A good review undergoes an edit, typically by an experienced editor. Prior to publication, a good review is checked for technical accuracy by the manufacture - the vast majority know they have no say outside this area. (And they don't.) Perhaps from a writer's perspective, the good review is one that is read - the best reviews read repeatedly.
Rather than post my own comprehensive list (believe me, I've had plenty of time to think about it) I'll tell you a little bit of what I try to do in my own reviews. Feel free to comment.
As I've said before I believe audiophile reviews are fundamentally expository writing and the root of expository is 'to expose.' It is a virtue to craft clear straightforward prose and anything that gets in the way of exposition is embelishment. Alas, I'm not Hemingway. Perhaps the harshest criticism I level against myself is my writing is (sometimes) baroque with convoluted sentences. But I do work at that. A good review is respectful of language, grammar and spelling.
A good review should be helpful to the reader. In addition to a basic product description you can find on the product Web site, I believe a good review should provide information about a product that may not be found elsewhere or is otherwise arcane. This is not easy. Often it involves a deep dive into the product, considerable research about relevant technologies, and interaction with the manufacture, trying to coax information from them. Most manufactures believe customers are not curious about technologies or not capable of appreciating technical detail. Also, most manufactures are very very leery of revealing anything they gauge proprietary, or might be copied, stolen, or be of a competitive advantage to another maker of a similar product. Those latter things do happen, more frequently than you might imagine and it is easy to understand manufacture disclosure reluctance. The industry is highly competitive. A good reviewer does more than scratch a product's surface and needs to be sensitive to manufacture concerns, strictly honoring NDAs. With diligence it is possible to ferret out product information that would not get published unless the reviewer took the time and energy to do so. I think it incumbent on a reviewer to do this. (And it sets a formal review apart from the 'drop by the showroom for a listen' type reviews.)
A good review includes the review context - the other equipment used in the system on which the review is based. A good review includes an account of product use, includes options the product offers and choices the reviewer made when using the product. This needs be somewhat balanced because describing every option or choice can make for tedious prose. A good review of an electronic component should use the power cords that came with it - that's the product. If there are problems or idiosyncracies with product usage, describe them.
A good review takes its time. After doing reviews over the years I am absolutely committed to the notion that a quick A/B/A product comparison has very limited value. I grant that some readers claim they cannot make a decision about a product without flipping a switch between it and some alternative. But a good review is not about that - it's not about choosing one product versus another. I believe one needs to live with a product for some time (more than a month) to understand and maybe appreciate its character - it doesn't matter how much experience you think you have.
A good review needs sonic descriptions of pieces of music the reviewer knows well. I agree with Stehno 100% when he said of a good reviewer: "possessing the ability to discern / interpret what they hear and conveying what they hear to the reader." Someone mentioned correlating what one hears with measurement - I don't do that; at best it is speculative. Infrequently do I claim to hear this or that and say it is because a product has some feature set. My approach to sonic description may be different from many reviews. I describe what I hear and experience playing a piece of music with the review product in my system; I don't describe the product, I describe the music, what I hear listening to it. Infrequently do I claim what I hear is because of something a single product claims to do. I'm listening to an entire system. There may be affinities or not among components. That usually is difficult to assess on a physical basis. (Maybe with cartridges, tonearms or a phonostage.) Only when obvious synergy obtains with one component and not another will I mention it.
Whenever possible a good review should include a sonic compare/contrast of the review product with a similar product in a similar price range. Most of my reviews do that but it is not always possible. One may not have anything similar to the review product or not have something in the same price range. I don't have the luxury of a backroom stocked with alternatives, so in my case I typically use what is in my system at the time. It's nearly impossible to borrow another manufacturer's component for the sole purpose of comparing it to the competition. (It's a reason you don't find many comparisons of equipment racks.) But where possible a good review does a sonic-level compare/contrast with an alternative that the reviewer has spent time with.
I could go on, as well as include my approach to reviewing albums. This is already way long. Thank you for reading about my review process to this point.
