The AB-1266 Phi TC offers impressive bass dynamics and open soundstaging, hallmarks of the Abyss sound.

The Story

The ultra-thin patent-pending TC (Total Consciousness) planar speaker drivers make the AB-1266 the highest resolution headphones on the planet, allowing you to hear the most subtle nuances within your music in a most natural way.

Our factory applied oven cured ceramic coating in a two tone luxury black color displays a more sophisticated look in person. Larger more comfortable ear pads improve the sound even further, in total taking the Phi's acoustic performance to even higher levels of sonic bliss.

From the very first note you will hear musicians and instruments in a whole new way. Voices appear out of nowhere and float in between your ears. Piano is in front of you to the left, singers in front of your forehead while drums are slightly forward of them. No electronic tricks, simply the natural sounds of the recording coming through striking emotional chords, that's Abyss. The AB-1266 Phi can convey the power of a huge symphony and the nuances of the quietest sounds in nature, a private concert for one.

The Craftsmanship

CNC machine and finish all aluminum frame components, produce the planer speaker drivers, and skillfully assemble the AB-1266 Phi TC with US made stainless steel hardware, all within our own facility in Buffalo, New York, USA. Deluxe leather carry bag made in California. Wooden box made in New York state.

Chassis consists of left/right side frames and adjustable two piece headband. No plastic parts to break, all components machined from solid aluminum for exceptional strength. Integrated resonance control for minimal added coloration, feauting high quality two-tone polymer ceramic finish, the hardest thin film coating in the world. Custom colors can be made to order.

Proprietary planar magnetic transducer design (Patent Pending) utilizing their very thin, very low mass diaphragm. Effortless dynamics and low level detail retrieval in the bass, mids, and highs with spacious sound outside of your head. A front row listening experience with stunning bass impact no other headphone can provide, like the finest loudspeakers in a private room.
