Yamaha Announces Flagship Headphone Amplifier for Hi-Fi Fanatics
New HA-L7A combines superior Hi-Fi audio technologies with sound advancements from AV receivers to elevate the sound of your favorite headphones and content to the highest level.
- Patented Floating and Balanced Power Amplifier — A total of four sets of 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. All circuitry, including the power supply, is completely independent of the ground, ensuring the effects of voltage fluctuations and external noise surrounding the ground are eliminated.
- 32-bit D/A Converter — Sparing no expense, the HA-L7A incorporates ESS Technology’s ES9038PRO DAC. The dedicated master clock on the device utilizes a crystal oscillator with ultra-low phase noise to attain the highly precise D/A conversion and features an eight-channel D/A converter housed inside the chip that applies four-channel conversion to the left and right sides respectively. Utilizing this four-channel bundle delivers exceptionally high-quality audio output with broad dynamic range and superior signal-to-noise ratio.
- Dual Toroidal Transformers — The power supply section employs two toroidal transformers with bifilar windings. One is for the minute-signal circuitry in the front stage and the second is for the amplifier section in the second stage. This design significantly reduces magnetic flux leakage while minimizing voltage variations, which in turn enhance the stability of the power supply.
- Sound Field Mode — Utilizing the same Yamaha CINEMA DSP sound field creation technology that is incorporated into many Yamaha AV receivers, the built-in Sound Field mode produces stunning results in the sound image. Six options of Sound Field are on-board to reproduce the optimal sound field for the entire scope of music and video.
