Great review. This looks like a terrific release, and I’m eager to hear them.
I don’t personally love the single-entry cable either. From time to time with headphones I enjoy switching channels just to see how it changes the presentation, and you can’t do that (I don’t think) with the single-entry cable (though it is more convenient in other ways).
Tangential question: Is there any example of a headphone measuring on the B&K on the low side of the preference curve at 8k? Every time I see measurements from that rig they look high at ~8k.
