He used to be the US distributor and retailer for Denafrips, endlessly praising their build quality, performance and value in his videos. Then the relationship was ended and he started bad mouthing the company and their products as being inferior, completely the opposite of his previous claims and obviously a case of sour grapes. So while he's repeatedly shown his biases many times, that doesn't mean that all of his observations are without merit.Absolutely. Any time, Anyone, is selling something, take it with a grain of salt. The one time I heard an MSB DAC, I didn't think it sounded analytical. System dependent, no doubt. I don't know if I would say his channel is necessarily driven by controversy. I do think he makes some legitimate criticisms of the high end audio industry.
