I’ve seen some of his videos.
If you’ve never heard, nor owned quality equipment, or are just starting your audio journey, he’s worth a watch.
Unfortunately, I’m sort of "way beyond" most of the garbage he seems to peddle/advocate/review. (I’m not trying to sound snobby, but when he tells me that a hybrid tube amp for $139 off of AliExpress is the best thing since sliced bread, well.....I can pretty much guarantee you it’s not.)
Most of my cables cost more than the equipment/gear he reviews.
IOW, I don’t really find his advice useful, (nor very accurate).
