TRUE SOUND
From the moment the sound is created to the time it reaches the human ear—Yamaha is there. It is the only brand in the world that intimately knows this process, ranging from the manufacture of musical instruments to professional audio equipment. And True Sound, which strives for sound that accurately reproduces even the very thoughts the artist puts into the music and the expressive view intended by the creator as is, allows you to fully immerse yourself in the sound and enter a profound musical experience, feeling as if you were right in the middle of the performance.
YAMAHA’S UNIQUE FLOATING AND BALANCED POWER AMPLIFIER TECHNOLOGY
Yamaha has optimized 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, minimizing 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 maximizing 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.
ELITE, ULTRA-HIGH PERFORMANCE 32-BIT D/A CONVERTER FROM ESS
Sparing no expense to realize superior sonic quality suitable for Yamaha’s ideal high-end headphone amplifier, we have adopted ESS Technology’s ES9038PRO converter, which is outstanding in the DAC industry for top-quality audio reproduction of minute signals. 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. This unlocks a greater sense of enjoyment in headphone listening, where you can intimately experience even background noises of the concert hall and the most minute details in the sounds of the instruments.
DISCRETE CONSTRUCTION AND BALANCED TRANSMISSION
All major stages after the DAC are unified with balanced circuitry and discrete configuration, achieving fully balanced transmission from the D/A converter output to the headphone jack. Moreover, balanced conversion is performed internally for ordinary single-ended (unbalanced) inputs, delivering the unique advantages of balanced transmission and amplification, such as minimizing external noise and sound quality deterioration, and applying them to a wide range of input sources. Additionally, when combined with headphones that support balanced drive, the common impedance of the transmission system is suppressed, further enhancing the signal separation that is crucial for quality headphone listening.
LOW-FREQUENCY REPRODUCTION AND REMARKABLE SPACIOUSNESS FROM DUAL TOROIDAL TRANSFORMERS
The power supply section employs independent transformers for the minute-signal circuitry in the front stage and the amplifier section in the second stage, and implements a separate power supply design that minimizes noise due to mutual signal interference. Moreover, usage of toroidal transformers significantly reduces magnetic flux leakage. Also, employing bifilar winding minimizes voltage variations, which in turn enhances the stability of the power supply, and achieves overwhelming spaciousness with powerful low-frequency reproduction.
SOLID METAL FEET FOR STABILITY
The distinctive L-shaped HA-L7A is supported by five conical steel feet at each corner of the chassis, with dampers cushioned between each foot and the bottom panel that effectively suppress any vibration, allowing firm and stable support even on a desk or tabletop. Together with the weighty 5.3 kg body, all elements work together to effectively eliminate unwanted vibrations to achieve focused and realistic sound reproduction.
SOUND FIELD MODE FOR UNPARALLELED IMMERSION WITH ANY CONTENT
The HA-L7A features the same Yamaha CINEMA DSP sound field creation technology that is incorporated into many of our AV receivers. The unit also utilizes 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. And one of the stunning results is the built-in SOUND FIELD mode. Adopting six convenient options that reproduce the optimal sound field for the entire scope of music, video, and other specific sources, it lets you enjoy all kinds of entertainment content with a full sense of realism and immersion that takes headphone listening into heretofore unexplored new worlds.
LOW-NOISE CIRCUIT DESIGN & HIGH-QUALITY PARTS
The HA-L7A adopts a low-noise design that isolates the three circuit boards: the main board that handles minute signals, the amplifier board and the amplifier, and the power supply board for the system. In addition, the main board is designed to eliminate any undesirable cross effects between the digital and analog signals through utilizing a multilayer board and thoroughly eradicating ground loops. Moreover, the MUSES72323, famed for its exceptionally low distortion and low-noise output, is used for the volume IC, while the power supply IC made by Analog Devices boasts low output noise with high ripple rejection. The converter section features the ES9842QPRO, made by ESS Technology. By using only the highest quality parts meticulously selected through repeated listening tests, we have achieved the most natural sound field reproduction possible.
THREE FRONT-PANEL HEADPHONE JACKS
The front panel of the HA-L7A features two balanced headphone jacks that allow you to fully enjoy the detailed, as-is high-quality of balanced circuitry, and one unbalanced headphone jack that reduces contact loss thanks to gold-plated processing. Famed NEUTRIK jacks are used for the XLR balanced headphone jacks, and Pentaconn terminals are used for the 4.4 mm 5-pole terminals, letting you connect your preferred set of headphones and unleash its full potential.
COMPREHENSIVE INPUT/OUTPUT TERMINALS FOR EXPANDABILITY
Featuring a comprehensive set of input terminals, including USB (type B), coaxial, and optical, the HA-L7A lets you connect a full variety of devices, such as high-resolution DAPs (digital audio players), PCs, and CD players. The amplifier also has built-in XLR and RCA pre-out/line-out output terminals, allowing it to serve as a D/A converter or preamplifier, providing exceptional connectivity and expandability options when using an external amplifier.
UNUSUAL DESIGN TO MATCH THE UNUSUALLY HIGH SOUND QUALITY
Following traditional audio principles and maintaining a low center of gravity, two transformers are mounted on the main frame and represented in the unique external design, invoking an impression of fine modern architecture. Furthermore, thanks to a vertical three-dimensional structure, the transformer is located immediately above the power supply board, minimizing the power supply path, contributing to a design that delivers both high sound quality and external elegance.
ELEGANT ROTARY DIAL
The robust weighty chassis is comprised of thick aluminum, and in addition to that exquisite main frame, aluminum is also used for the master volume and mode selector dials. Moreover, an abrasive sandblasting process has produced a high-grade textural feel, contributing to the elegance of high-end audio right down to the smallest detail—delivering a supremely tactile experience when using the HA-L7A.
OLED DISPLAY WITH BRILLIANT VIEWABILITY
The top panel of the unit features a gorgeous OLED display that provides a variety of important information, including the input source, its sampling frequency, volume, and the name of the SOUND FIELD mode used—all in an exceptionally easy-to-read manner. The display automatically turns off after being operated, eliminating any distraction or slight undesirable effects on the sound.
