Yamaha HA-L7A High-End Headphone Amplifier

Introducing the Yamaha HA-L7A high-end headphone amplifier.

Dive in, immerse yourself, and newly experience the full emotion and excitement in all your entertainment.

The Yamaha passion to constantly create and innovate has scaled sonic heights for over 30 years, fusing superior Hi-Fi audio technologies with sound field advancements from their AV receivers.

Yamaha has optimised its patented Floating and Balanced Power Amplifier technology for this headphone amplifier. A total of four sets of power amplifier circuits on the plus and minus sides of the left and right channels of the output stage are floated from the ground, resulting in thoroughly symmetrical push-pull operation of the output stage.

The headphones can be driven without altering the amplifier configuration between balanced and unbalanced, minimising any sound quality discrepancies due to different output terminals.

Moreover, all circuitry, including the power supply, is completely independent of the ground, and all effects of minute voltage fluctuations and external noise surrounding the ground are thoroughly eliminated.

By maximising these sound quality advantages, the amplifier achieves a natural and fatigue-free sound that lets you fully lose yourself in your entertainment, even when listening for a long time.

In order to fully convey the contrast between serene stillness and powerfully dramatic motion in the sound, the amplifier adopts two toroidal transformers and boasts a unique, highly rigid construction. Accepting no compromise, Yamaha have achieved low frequency response with outstanding response to minute sounds, luxurious volume, and extraordinary transparency, to ensure accurate reproduction of all kinds of content with dynamic and realistic sound.

HA-L7A features the same Yamaha CINEMA DSP sound field creation technology that is incorporated into many of their AV receivers. The unit also used the unique signal processing and multi-channel expansion technologies Yamaha has developed and cultivated over its many years of designing AV components — now brought into the headphone field.

Yamaha's unique SOUND FIELD mode and tremendous sound field recreation could only be accomplished through an unwavering commitment to the best in sound reproduction. With a realistic, natural sound field that allows you to completely lose yourself in your listening, HA-L7A delivers a new entertainment experience that had previously been unexplored with headphone amplifiers.

Enjoy a truly immersive feeling - as if you were entering the very performance space of the artist.
