If you're an engineer, it very well might be fascinating, perhaps. Measurements are good, as is factual understanding, but overwhelming the reader with numbers and concepts does not facilitate comprehension. It's not very much fun either. The material must be personable and entertaining for the targeted reader also, which makes the responsible reviewer's job pretty daunting. Let's face it.
Most reviewers are quite enthusiastic about their equipment.
They should be, and it is very possible to get carried away. It's also easy to play it safe and avoid controversy by not commenting on sonic attributes and personal reactions, instead seeking guidance from the book reports sixth grade drove through our life so thoroughly. A good reviewer, a reviewer worth the time to read his or her work, must balance these objective measurements with personal experience, hopefully even relating the two, while taking pains not to misrepresent a product as something that it isn't. It does not serve the reader to have a reviewer exaggerate sonic differences if, by every measurement, those differences may be truly minimal. Nor does it serve the reader to have reviewers ignore differences that might be relevant.
