Typically, an audio reviewer requests a review unit from a distributor or manufacturer. The Vibe unit tested here was sourced from a reader. Most audio reviewers/reporters do engage in some dialogue with the manufacturer when publishing a review; ASR operates on a different principal in general, but has done so before.
Sutherland probably employs about 5 employees; most of those would likely be production workers. I'm fairly certain that small boutique shops like Sutherland don't spend their days scouring the Internet for every possible mention of their products. ASR has never reviewed a Sutherland product before; ASR reviews few high-end phonostages which are Sutherland's specialty. Most ASR readers would be disinclined to spend over $1000 on a phonostage, per the comments I've seen.
So, no, I would not expect Ron Sutherland to have heard of ASR. Even if ASR has a wide base of online readers, it has had zero impact on his commercial interests up to this point.
But more to the thrust of the question, why would it be so odd to expect that Amir might want to call Ron Sutherland? If the point of the site is scientifically based inquiry of audio products, I'd think such a call would further the interests of everyone involved rather than just assuming that Ron would know that ASR has just reviewed a reader-owned product. In particular, I think the dialogue would be enlightening regarding the test protocols ASR uses for phonostages, which have been a moving target over the past few years.
Ron's a nice guy, a thoughtful and careful engineer, and a well-established designer in his niche, but I do not presuppose that he's thinking about what ASR has to say right now.
