It's really bad for HDR monitors, where an edge lit "fake HDR" monitor can get a 7, while failing the basics that are necessary to give a proper HDR experience. Something like TFTCentral or HardwareUnboxed's HDR checklists, and just straight up failing monitors that don't meet all the requirements would be much better than their current (imo misleading) system that can give good SDR monitors high HDR scores, when they're terrible at HDR.
For other stuff, I usually check Wirecutter and cross-reference it with Reddit reviews.
I also have noticed that Wirecutter seems.. less qualitative (?) since they got bought by The NY Times.
Here's a good video detailing some of why: https://www.youtube.com/watch?v=Fa1y9JRip68
Head-fi is full of woo that thinks that you need a four digit power cable, and a rare wood volume knob.
Some of the videos from High End - audio show in Berlin right now are just mind blowing.
$12,000 power cables. Speakers that are $345,000 - each. Preamps that are the size of 4U rack servers. "This device streams from Tidal and Qobuz to your system. It's $39,000."
I cannot recommend audio science review[0] enough. They're the opposite. All about objective measurements and rigor. None of the bullshit.
