HPA-KG NARU
Características
- Featuring KUROGAKI wood side panels and an Ayasugi-inspired metal mesh protective grille, the unit is stylized to reflect the beauty and power of nature
- The signal amplification stage employs paired JJ ECC83S tubes, known for their rich and resonant sound characteristics
- Two pairs of Takatsuki TA-300B tubes are utilized in the power stage, delivering powerful driving force and dynamic high-quality sound
- Circuit design features Lundahl input and output transformers, the latter constructed with amorphous alloy cores
- Three-position impedance selector switch allows you to choose appropriate impedance based on headphone characteristics and desired sound quality
- Two analog pre-outs (unbalanced RCA and balanced XLR)
- Three analog inputs (unbalanced RCA and two balanced XLR)
- Includes four replacement TA-300B vacuum tubes and a function explanation plate to aid in the use of the amplifier’s front panel dials and switches
- Amplifier complies with the new safety standard IEC 62368
- Included limited-edition AW-KG NARU headphones feature housings crafted from precious KUROGAKI wood
- Includes two detachable fabric-braided headphone cables with A2DC (Audio Designed Detachable Coaxial) connectors at the headphones: a 2.0 m (6.6') cable with gold-plated 4-pin XLR-M balanced connector and a 3.0 m (9.8') cable with 4-pin XLR-M balanced connector
- Additional set of ZMF Universe Hybrid earpads is also included for a unique alternate listening experience
- Japanese craftsmanship: All Audio-Technica wooden headphones are hand-assembled in Tokyo
- Headphones come with a wooden storage box adorned with KUROGAKI wood
