“I don’t think..” Ok, you’ve made a number of assumptions and we don’t share the same priors so I’m unable to follow you to your conclusion.
I think you are underestimating the importance of perceived premium combined with the pressures of cost accounting, but I do think that is pretty normal for ‘audiophiles’ which is their target market.
Which assumptions? The weight reduction on the S2 is documented and the cable’s 65W rating is what the tester confirmed.
If the argument is that B&W deliberately chose a thick cable to seem premium, it doesn’t square with them actively slimming down the headphones. B&W are primarily a speaker company, their USB-C product range is basically just a few headphones and earbuds.
More likely they just sourced a generic cable that happened to support high wattage and didn’t think about the mismatch.
Either way, we’re deep in the weeds on B&W’s cable procurement now. The root point is that USB-C is a mess. You can’t tell what a cable supports by looking at it, and even premium manufacturers are shipping cables that don’t do what you’d reasonably expect.
That’s exactly the problem the Treedix from the article solves.
