I agree it’s a good resource. It’s just not the final authority on sound quality that it’s fans make it out to be. The same holds true for a range of audio review sites. The same issues that other review sites have about hazy commercial engagements and biases also apply here.
on the linearity vs noise question, the both could be equally important or, depending on the application, one could be more important than the other. Pretending that a single combined noise and distortion variable captures everything about measured sound quality is misleading
