I think this video is AI generated click bait and I think you can probably find material with the same voice that talks about how completely amazing six figure amplifiers can be . I think a lot of these AI generated videos are popping up that are geared to play to a target audience and it’s preconceived notions. Always a market for telling folks what they want to hear.
If you look at the specifics, he’s right, you’re going to be disappointed if you don’t properly match your amp and your speakers. The pass labs amp won’t properly drive power hungry speakers. The lower tier D’Agostino is, according to the video, a good performer but not “life-changing.“ Anyone expecting an electronic opponent to change their life is apt to be disappointed. If you like a sweet, colored sound, boulder may not do it for you. Well, that’s true.
I suppose as a major theme the video says that this equipment is well designed for its intended purpose but must be put in a properly matched system that suits the owners subjective preferences. And while there are gains to be had, sometimes they are subtle and not “life-changing“. So maybe there is a lesson in that, if someone didn’t already know it.
