ASUHA Ref.2 earphone re-cable

The ASUHA Ref.2 earphone re-cable uses BriseAudio's original 8-core cable, which is also used in the ASUHA-LE and ASUHA Rh2+.にも採用されているBriseAudioオリジナル8芯ケーブルを採用。 音質に最大限配慮しつつも実使用上の取り回しにも配慮したASUHAシリーズのトップエンドとなります。

The ASUHA wire has a very high potential in sound production, with a wide range while maintaining the high resolution and low distortion that characterize BriseAudio at a high level.

ASUHA Ref.2では、YATONO開発で得られたノウハウを注ぎ込み、従来製品トップエンドに採用しております特殊な電磁者吸収シールド材に加え、 カーボンナノチューブ素材、他にも様々な素材を組み合わせることによって 従来のRef.シリーズから1歩進んだ音質を実現しました。 それにより、ASUHA線材のポテンシャルを最大限伸ばすことが可能となりました。
