This is like asking is MQA good or not.
Re. @curtdr and @pedroeb comments... anyone who thinks Mr. Amir isn't "... irrelevant opinionated egotistical jackass garbage." (and there's no need for this kind of commentary in the audiophile world imo), is self exposing. Amir is entitled to his pontificating and if you like him, great.
1. Randy has a lane. While I fast forward his intros (annoying music and intro fodder) and only watch a some of his reviews. (I am not a Paetron of his. I am of a couple of others whose reviews fall more inline with my interests.)
2. I had an application / location where I didn't want to spend a lot of money. Between Randy, Zeos, and others, I learned about Fosi amps and Jamo S 803 speakers. Pretty impressive for background music and I spent less than $350.00 and am very happy with them. Randy discussed the Fosi amps that got me looking.
3. It's basically still a free country and you can choose what you watch, read, etc.
4. I've only been nosing around these forums for the past 2 years. The outliers and know-it-all folks can be ignored.
5. Randy occasionally reviews some higher end equipment.
6. Re. YouTube reviewers, I appreciate Hans Beekhuyzen, "Z reviews" (mainly headphone gear), John Darko, Currawong, & Josh Valour to mention a few. All have their lane.
As Han's always concludes his videos, "and whatever you do, enjoy the music!"
