The BHSE has been surpassed IMO. Try the Grand Cayman if you get the chance. I think it’ll end up priced right around the Kerry T2.

If someone could make a headphone that sounds as natural as the 9k and stages as naturally as the 9k but with the visceral physicality of the 1266, that’d cover the bases for me. With the T2 the 9k gets a taste of that, so that could really be endgame, but it isn’t the same as the 1266 of course. I have the same experience switching between the two. 1266 sounds unnatural, recessed in the mids, and boomy when going from 9k to 1266, and the 9k sounds totally flat and boring going the other direction, but it doesn’t take long for me to adjust, and the 9k’s natural staging is starting to win me over. Both headphones are absolutely the top tier performance you can get from a head-fi system, so I hope my comments aren’t taken as otherwise.

And if you go down the speaker rabbit hole, if you haven’t already, check out Kharma speakers. It’s the first experience I’ve had that I felt surpassed Magico M Series and Rockport Lyra. I’d have to do some A/Bing to confirm, but my most recent experience with Kharma was one of the best experiences I’ve had in audio.
