A1-JA is the limited edition of A1 single-ended Class A Tube Headphone Amplifier in a hand-crafted glass cabinet.


Driven in pure Class-A mode, the premium grade Genalex Gold Lion ECC82/B749 tubes - chosen for their sonic purity and low noise - provides the foundation for Athena A1’s single-ended front end.

A full wave rectifier is followed by LC smoothing filter with huge and powerful audio grade capacitor.

The Class-A MOS/BJT hybrid output stage is extremely solid and robust (only the renowned BJT is considered) and it is a great complement to the single-ended triode front end. Together, they render music that flourishes with all the harmonic hues of live music.


A1-JA Limited Edition - SE Class A Tube Headphone Amplifier

The output stage exhibits extremely low output impedance, which ensures compatibility with low impedance headphones; and its high output voltage swing also allows Athena A1 to effortlessly drive high impedance headphones as well.

Elegantly presented, the Athena A1 features a strikingly attractive visual design, glass exterior, and state of the art construction. This innovative and bewitchingly musical vacuum tube headphone amplifier may well have re-written the book on SET (Single-Ended Triode) design.

Handcrafted to Perfection


Enclosed in a 12mm crystal glass stand, it requires super-high precision and 100% focus handcrafted by glass artisan, so to match the crystal clearness of the music -

It's an ART - a perfect fusion of industrial design and acoustic engineering
