I’ve never owned an Abyss but I do think the 1266 is worth owning for someone who can afford a second flagship headphone. (The first should be an honest flagship like an LCD, HiFiman or Focal). Despite the fact that the 1266 measures poorly in virtually every way, it really is a headphone that defies measurements. For some reason, it’s still one of the most detailed headphones I’ve heard. Maybe it’s the transients or something. And of course they are one of the only headphones ever made to specifically take advantage of an air channel to give you massive dynamic bass that is unmatched. If you throw on tracks that already sound huge like Futurerave, it sounds like you’re at Tomorrowland. It’s the ultimate EDM headphone.

The Diana I just never understood. The price is shocking for what sounds like to me a closed back headphone with middling everything. I’d pay 300$ for it. Even then I might still opt for a used r70x.
