That’s a shame, he really is full of it. I’ve seen several videos by him over the years and while I can’t categorically prove that he’s not just misinformed, rather than a deliberate liar and scam artist, it’s difficult to imagine he could ever get some of his products to even function if he really believes all the nonsense he spouts!
There’s a long history of audiophiles and DBT/ABX, going back to the early 1980’s and the famous Carver Challenge. Top reviewers from the most respected audiophile publications were challenged to tell the difference in a DBT between a $400 amp and top of the line amps costing 10+ times more, that they all raved about. They were certain the challenge would be easy but they completely failed. For a while they tried to ignore the whole thing but as it had quite an impact on their credibility they had no choice other than to start falsely claiming DBT/ABX tests don’t work and obviously, not to participate in them again. Paul McGowan is just repeating the same tired and debunked falsehoods invented by others about 35 years ago!
It’s a test that’s been widely used for around 80 years or more. It’s extremely accurate and reliable, based on a simple mathematical principle and represents an incontrovertible standard of proof. Which is precisely why the audiophile market avoids any mention of the Null Test and why you haven’t heard of it. There’s even excellent free null test software that does all the work for you.
Again, it’s been done countless times, plus of course null tested and James Randi even offered a $1m prize to anyone who could tell a difference in a DBT. It ran for 15 years or so and was never claimed. Not to mention, the modern world depends on cables and there’s few things in human history that have been researched more thoroughly and are understood as comprehensively. All the audiophile companies combined have contributed absolutely nothing to the 140+ year history of governments and billion dollar companies’ huge R&D in this area, except of course for snake oil, in which they’ve contributed everything!
Btw, did you read the DSD vs PCM study I linked to previously?
