The JPS Labs: Abyss AB-1266 Impressions Thread

@Ciggavelli We tested various sizes on the new leather headband. If you hang a brand new headband on a stand, forgive it time, the leather itself will stretch, so the stock ring size (213) was set to fit the leathers final resting length. A brand new headband might be a bit tight up front, but it will break-in.

All the people you know are guys who already owned AB1266 with the old style headband that's all stretched out, basically hitting the top screw on the metal frame. Sorta fits like an old shoe, then upgrade to a new virgin headband, didn't put any time on it, lack of patience sort of thing which I get, and go right to changing the rings. Not something we anticipated, but definitely saw it happen.
I hear you, but nobody is doing that. It’s much easier to just use the one size up o-ring. Like much easier

Has anyone tried the AB1266 Phi TC with the Feliks Envy? I loved the Envy with the Susvara.

I spent some time with the TC and a DNA Stellaris. There wasn’t enough current to fill out the guts of the TC, though some of the DNA magic still came through. Fingers crossed that some day Donald makes a stronger amp that will gel with low efficiency isodynamics!

Joe and team, the AB1266 Phi TC never cease to amaze me. Due to my son's hockey and life in general, I've been away from music listening for most of the month...tonight was a rare night off and I'm sitting down to listen to Neil Young's new album and it is like my first time putting these amazing headphones on my head! Such an expansive and speaker-like sound with incredible balance and transparency! Definitely something to be experienced!!! :L3000:

For those with the old style headband and who do not want to spend a bomb on a new style headband

I’ve tried using rubber o rings and using a splice connector/crimp, its dead easy, and cheap to replace the o rings

My pics depict o rings of OD 30mm and CS 3mm. Crimp is 2.5mm. You may find the parts locally, I just got them from AliExpress, just over a sollar

Can you explain the process as to what you have to do and tools to use.

Just found this amazing album, never been this excited and impressed for a relatively new band in a long time. Great music and production quality, sound glorious with 1266 TC.

Took some time but finally built a system around the 1266



1266 have quickly become my go to headphones for metal and just looking at my Roon statistics, my metal listening hours have gone way up since getting these. Highly addictive and making me discover new genres and albums like this one

@paradoxper approved this post. Also, sweet!

How's the Studio B/Abyss pairing? I've had some experience with it driving efficient planar but nothing close to the synergy it had with a dynamic driver headphone.
I am actually using the Studio B as a preamp to feed the CFA3 SS amp and 1266 TC is plugged into the CFA3. Studio B will get the TC loud enough but the synergy is not great, especially the bass doesn't feel quite filled out. Overall, it feels a bit hollow/anemic directly out of Studio B.

CFA3 by itself does a great job of driving the TC but I usually run it with the 300B pre. I have done some (not so detailed) A/B but to my ears adding the tube pre seems to add more body to what might be considered as a slightly dry sound.
