EnigmAcoustics Athena A1 Single-Ended Triode Vacuum Tube Hybrid Headphone Amplifier
Sold Out & Discontinued
The Athena A1 is the first headphone amplifier from EnigmAcoustics and an audiophile’s dream. From the three dimensional soundstage to the ability to faithfully articulate voices and instruments, to separate and fix them in space, the Athena A1 is an engaging and musical headphone amplifier.
- ECC82/12AU7 triode vacuum tubes for sonic purity and low noise
- Single-ended front end
- Solid yet elegant glass design
- Drives low & high impedance headphones
EnigmAcoustics chose ECC82/12AU7 triode vacuum tubes for their sonic purity and low noise, driven in pure Class-A mode, to provide the foundation for Athena A1’s single-ended front end.
A full-wave 6CA4 vacuum tube rectifier is then employed, followed by an LC smoothing filter.
While the Class-A MOS/BJT hybrid output stage is extremely solid and robust, it is a great complement to the single-ended triode front end; and together they render music that flourishes with all the harmonic hues of live music.
Compatible with low & high impedance headphones
The output stage exhibits extremely low output impedance, which ensures compatibility with low im90pedance 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.
