Audio Science Review, bs or something else

Ok, I’m a long time lurker. I own BHK 250 and the pre and the sound is wonderful.
This ASR website rated the DS has poor testing numbers.
I know the true test is what it sounds like . But, can someone explain (I know it’ll be complicated ), do we want great test numbers or is some distortion ok? Why is that? Is distortion ok with some electronics but not others ?
Thanks
Dave
Btw I am researching DACs and streamers. I have a little knowledge but a large curiosity.
