As a scientist and engineer I think ASR is a welcome addition to the hobby and industry. First, it provides depth in comparison to the surface-grade preferences and coded adjectives that are the stock for subjective discussions and reviews. Second, it is important to have a comprehensive debunking forum that shows nonsense and snake oil through tests and an interrogation of the underlying arguments that justify things like power cords, conditioners, and expensive interconnects. Finally, there are deep discussions of core matters related to audibility and preferences (very much science) as illustrated by the recent discussion of preference curves for headphones arising from a Sean Olive AES paper. Many of the participants are designers, engineers, and scientists themselves so there is an inevitable depth to the discussions and reviews.
I encourage more people to use ASR as a resource to learn more about how systems are engineered, tuned, and the underlying science that backs up those methods!
