Woo Audio WA33 Fully Balanced Headphone Amplifier- JPS Labs Edition

The newly developed WA33 is a state-of-the-art, fully balanced headphone amplifier that raises the bar in setting a new reference in music reproduction. 
 
The WA33 employs a true fully balanced design in a compact form factor, featuring a quad (four) of 6C45 tubes for the driver that pushes a quad (four) of 2A3 tubes for the power, and all in direct-heated triodes. It delivers high power to drive demanding headphones to their full potential while maintaining a low noise floor.

The WA33 is a dual chassis design with separate power supply section. This approach eliminates any interference to critical audio components. Additionally, our internal coupling architecture (ICA) technology allows the WA33 amplifier to merge with the power supply unit without an external umbilical cord- two components as one. The ICA shortens the signal path and thus significantly reduces unwanted electrical interference and raises sound performance to a level beyond what anyone has previously experienced in a headphone system.
 
The WA33 reveals the most delicate detail with the highest level of refinement. Complex music passages are handled with ease and authority. The expansive soundstage, holographic imaging, and rich tones that are pristine, natural, and vivid create a sense of realism that gives the user a euphoric listening experience. With the WA33, music comes alive!

This special JPS Labs Edition features internal Alumiloy® wiring by JPS Labs, noted for their unique ability to provide life-like clarity and full range coherent sound from the lowest lows to beyond audibility [JPS Labs, the parent company of ABYSS Headphones, designs and manufactures cables for everything ABYSS].

Also part of this JPS Edition are a full upgrade compliment of KR Audio power tubes, a quad set of 2A3HP and a 274BHP tube rectifier. These High Performance KR tubes were developed by JPS Labs and KR Audio specifically for ABYSS headphones, providing hard hitting powerful bass with all the subtle details and life-like qualities to music that only tubes can.

Abyss Headphones considers the WA-33 JPS Labs Edition to be finest tube headphone amplifier money can buy to mate with their AB-1266 Phi TC headphone, or any other high performance headphones that appreciate power and grace.
