Diana TC Signature was developed specifically for the most experienced listener and audiophile who appreciates listening to music at the highest levels of resolution and refinement.

The engineers at Abyss take their love of music to an extreme by incorporating coveted conceptual designs in precision CNC machining, head acoustics, and planar magnetic speakers into this exciting new headphone. Diana TC Signature has the speed of a huge horn speaker system; a deep, airy, and layered soundstage with smooth clear highs that extend out into space, a distinctive midrange and vocals layered within the depths of the soundstage with deep and defined subwoofer bass.

Diana TC Signature is the most open back Diana in the series, allowing greater air flow and freedom of motion to this next generation TC planar speaker. Newly designed aluminium frames are 100 grams lighter and more acoustically transparent to the beautiful detail in sound. Fitment to nearly any head shape has also been further improved.

Combined with Abyss bass ported lambskin ear pads, foundational low bass is surprisingly impactful way down into the subsonics, so much so you can feel it! TC Signature performance to size ratio is the highest in the world, and the hallmark bass their flagship AB1266 headphone is noted for shines through. If you're an existing AB1266 owner with electronics to match this headphone is drop in ready, tube or solid-state amplification.

World class sound, industry leading build quality and luxuriously appointed fine leathers and materials for all day comfort, the TC Signature headphone deserves the highest level of electronics and cabling to compliment it's nearly limitless resolution. Let our experts help you build a dream system to relax to at home, work, or travel.

Features:

• Ultra-slim, ultra-light boutique headphone sculpted from aircraft-grade aluminium for incredible strength
• Next generation Abyss TC Signature 63 mm planar speaker drivers are built in-house and utilise a large high-tech neodymium magnet and ultra-thin planar speaker diaphragm to reproduce extremely fast transients and powerful bass that goes down deep into the sub bass below 20 Hz (US patent #10,455,343). The sound is similar to a big speaker system with subwoofers, only more intimate.
• Next generation CNC machined aluminium frame assembly with open back tuned Fibonacci hole pattern enhanced for TC Signature to maximise bass response and extend openness and soundstage depth well outside of your head.
• Beautiful high-end leather headband with Ultrasuede® sling suspension for all day comfort
