Abyss 1266 Total Consciousness - when the name checks out
Around two months ago I got the 1266 Phi CC, and I loved that - it had a pretty synthetic sound all around (and I do enjoy that personally), with insane detail, pretty large but very well defined staging. There were two issues with it really - for one, the unit I got was second hand and at an amazing price, but in a pretty well worn condition, and me being the looks-obsessed-audiophile that I am, it bugged me. The second is the existence of a newer and better model, that being the 1266TC, so the FOMO was kicking in pretty hard.
@Abyss Headphones also offer customization, which pretty much goes as far as your imagination and wallet does - a custom color adds 1000$ to the bill (which is where I stopped), but you can get custom grills, materials, leathers and well... pretty much anything. It is very pricey and I'd say only really worth it if you are 1) certain that they are for you and 2) pretty nutty about looks as I am
Fitting the 1266TC has become almost a meme in the audiophile community - I happen to have a pretty big head, so the 1266 fits me well, but I certainly can't get that effect where they "sit" on top of your head, barely clamping on your ears. I'm not sure if that would have a significant impact on the sound, but I've come across a few others owners who wear it the same way I do, so take it as you will
The build quality of the 1266 is nothing short of phenomenal, and I absolutely love the industrial look and vibe that they have - I love the MMR Thummim for the same reason, the full metal look just resonates with me, and has made me an instant, tryhard fanboy of both brands. Luckily in both cases the sound that they produce matches the nutty, industrial, hardcore look of the headphones.
On sound, I'd actually say the 1266 TC is more of a blend between the Diana Phi and the 1266 Phi CC as opposed to a direct upgrade of the latter. I can definitely see myself owning one of these as well, as there was something appealing about just how industrial and artificial they sounded - listening to hard rock on them was an unparalleled experience.
The
bass on the 1266 TC remains to me the best bass any open back has produced (or at least from the ones I've heard). It has quantity, it has impact, depth, texture and that oh-so-satisfying decay. The Diana Phi approaches it in a way, but the 1266 comes in with more quantity and more quality. To my ears it comes across as bass you can hear as opposed to that bass that open backs tend to produce that you "feel." It might have to do with the housing - they isolate a little better than other open backs I've heard, so maybe Abyss has found a way for higher pressure build-up.
The
midrange on the 1266 is a blend of the Diana Phi and the 1266 Phi CC - the Phi CC was especially cold and sharp in how it presented vocals, while the Diana Phi has taken a bit more from the V2's warmth in that region. The 1266TC remains quite cold and uninviting in the midrange, offering technical performance above all else - the clarity, detail and texture are nothing short of incredible - each sound and instrument is rendered with obscene precision, to the point where it's giving you the option to single it out and listen to nothing but that.
That of course comes at the expense of a more natural and realistic sound - the 1266TC is a headphone that wants to be heard in that it adds a fair bit of its own personality to the track. It isn't a transducer that disappears to allow you to just enjoy the music, it requires a certain "total consciousness" of the fact that it is there reproducing the sound.
In terms of vocal presence, I'd say it places vocals on the same plain as instruments, maybe even slightly further back.
The
treble on the 1266TC follows suit - the level of precision and sobriety that it exhibits is incredible, allowing you to hear every nuance - the upper treble is quite overloaded, which hits the sweetspot for me, but would definitely hit on some people's sensitivities. The speed of the treble is quite remarkable, in many ways reminding me of the Sony IER Z1R - something to marvel at really, and Abyss have placed it quite forward in terms of raw quantity, so you do need to want treble to enjoy these, and quite a bit of it too.
In terms of
technical ability, the first second and third thing that needs to be addressed is the level of detail that these produce - you can hear, and I kid you not, anything. No IEM I've ever listened to has been able to produce this much detail, and IEMs are generally speaking my reference point for overloaded detail. When I was first listening to them I couldn't even focus on the music because of the sheer amount of stuff that was happening. I'd absolutely recommend that you listen to these at least once in a lifetime for the amount of detail if nothing else.
The staging of the 1266TC follows in the footsteps of the two Diana's in a way - you can clearly here where its boundaries lie, and everything occupies an extremely specific place within the space they create - the height is nothing short of incredible, and the width is good, but because of said boundaries, it might come across as somewhat narrower than something like the HD800. It is my preferred kind of staging for headphones tbh, as I really can't deal with that borderless presentation.
Instrumental separation is just as exaggerated on the TC as umm... everything else - every instrument and vocal has a life of its own within the performance as a whole.
Verdict? Everything about the 1266 TC just screams metal - from the build, to the feel, to the music it plays especially well with. It is anything but a stereotypical open back, in how engaging and intense the sound is and just how artificially precise its technical ability is. It is a transducer that adds a lot of its own flavoring to the mix, and achieves incredible performance at the expense of a more natural and laid-back presentation.
It fits me and my preferences exceptionally well, and tbh I would've been happy even if there were no improvements on the 1266 Phi CC, but I'd have to go with a cautious recommendation - I can see it not fitting the preferences of a lot of audiophiles out there as it is anything but traditional.
