If that is the case, claims in the video are not worth much. Speaker's words are supported by speaker's words only. It appears to be one of the videos that is there to attract clicks for whatever reason. It goes on for 16 minutes of saying virtually nothing substantial which is another red flag that trustworthiness is questionable at best. I understand that the speaker has a reputation of being valuable in Hi-Fi world, but his claims are, so far, only claims with not even a hint of proof that what he is saying is remotely true.
