I actually discovered Bryston when Verion cables appeared around 40 years ago and they were the local distributors. A $75, 1 metre patchcord was a fortune back then but they were properly made. My advice after all these years of researching the topic is that you should never pay attention to anything coming from a company in the cable business, unless it's Bryston's people. This is for the simple reason that they only sell cables because so many customers asked them for a product they could buy with confidence. Otherwise, stick to proper engineers for technical information. There is a little complexity to the subject of cables but nothing like the opportunities for continuous improvement that the many charlatans would have you believe.
If you have the patience to make your own, there is a lot of money to be saved and the convenience of getting just the right length as well.
Looking into how the human brain works is very helpful when dealing with some of the differences we can hear that are actually artifacts of our perception in the moment, based on what we believe to be true. I've been caught out hearing a significant improvement when no change had been made. It's a bit embarrassing but that is how our minds actually work, for better or worse.
