High-performance amplifier providing the ultimate sound quality experience

The AMP-8510A is an innovative semiconductor Class-A single non-reverting amplifier designed to exceed the expectations of music lovers. It is a product of technology and dedication to push the limits of sound quality.

A choice of semiconductors, unlimited sound quality experience

The AMP-8510A offers a choice of the following four output semiconductors:

MOS-FET (Metal-Oxide-Semiconductor Field-Effect Transistor)

MOS-FETs are widely used in audio amplifiers because of their very high switching speed and efficiency; their distinctive advantage is their high input impedance and low output impedance. This gives MOS-FETs the ability to deliver large currents with minimal degradation of sound quality.

Three types of semiconductors, silicon carbide (SiC), gallium nitride (GaN-FET), and ultra-low output impedance MOS-FETs, each have different sound quality characteristics that make them suitable for specific musical genres. The following sections detail the characteristics, reputation, and evaluation of each, as well as which music genre they are best suited for.

SiC (Silicon Carbide)

Sound quality characteristics:. SiC devices are known for their fast switching speed and high efficiency. As a result, the sound is very accurate, clear and detailed. High frequencies produce a clear, transparent sound, mids are articulate, and lows have a tight attack with little distortion.
Ratings:. SiC semiconductors are highly regarded for their precision and detailed sound quality and are often used in high-end audio amplifiers. Audiophiles appreciate their ability to faithfully reproduce the subtle nuances of music.
Best Music Genres:. Ideal for classical music, jazz, acoustic performances, and other music where fine detail is important. It also performs well with music that has complex instrument configurations and a wide dynamic range.

GaN (Gallium Nitride)

Sound Quality Features:. GaN-FETs are characterized by ultra-fast switching capability and low power dissipation, resulting in a dynamic and vibrant sound. It has very good transient response, very fast switching capability and efficient power transmission, resulting in a dynamic and powerful sound quality. It is characterized by an energetic and vibrant sound with good sound rise and response.
Ratings:. GaN-FET technology is attracting attention in the audio industry as a next-generation semiconductor material,It is considered to be the most advanced, and is especially favored by users who demand high efficiency and powerful sound. Compared to conventional silicon transistors, GaN-FET technology is considered a step ahead in terms of energy efficiency and sonic accuracy.It is especially appreciated in amplifiers where efficiency and performance are important.
Best Music Genre:. Ideal for genres that require dynamic range and energy, such as rock, electronic music, and pop. It is particularly well suited for contemporary music that demands punchy bass and crisp highs.

Ultra-low output impedance MOS-FET

Sound quality features:. Ultra-low output impedance MOS-FETs have extremely low impedance in the output stage, providing very high speaker drive capability and smooth, stable sound quality. The overall frequency response is flat, with particularly strong and clear reproduction of sounds in the bass to mid-range.Warm and smooth sound quality, providing natural midrange and deep, rich bass. Low output impedance minimizes loss of signal strength, resulting in rich, powerful sound. Low distortion,extremely smooth sound quality, even in the high frequencies, for a comfortable listening experience.
Rating: 1.0 Highly valued by audiophiles because it offers even greater sonic freshness and stability than conventional MOS-FETs. It is especially preferred in amplifiers that strike a balance between technical precision and musical warmth. It is favored by audiophiles seeking a relaxed and natural listening experience because it delivers a sound that is both delicately reproduced and smooth.
Best Music Genres:. Ideal for genres that require warm, rich sound quality, such as blues, soul, and classic rock. It is also suitable for vocal-oriented music where natural midrange is important.

The above four types of semiconductors are the crystallization of semiconductor technologies that play an important role in high-performance audio equipment. These technologies have become indispensable elements in modern high-end audio equipment, providing a richer and clearer musical experience. The unique characteristics of each semiconductor allow you to enjoy minute differences in sound quality and achieve the ideal sound.

Unparalleled Sound Quality and High Precision

With an output of 10W at an 8Ω load, the AMP-8510A has a distortion of only 0.025% at 1W and a frequency response from an astonishing 10Hz to 100kHz. Furthermore, it has an astonishing characteristic of passing up to 1 MHz in sine wave, allowing musical details to be expressed with breathtaking clarity.

Unparalleled driving power due to direct-coupled design

The greatest feature of the AMP-8510A is that the output semiconductors are directly connected to the speakers without any intermediary connection between them. This design is impossible to achieve with complementary PP (push-pull). The output power is 10W and the bias current is 1.8A, which requires a larger bias current due to the characteristics of a single Class-A amplifier. Due to this direct-coupled design,The direct-coupled design allows the fine nuances of sound that were previously inaudible to be reproduced clearly, even with SATRI-LINK connections using current signal transmission. The benefits of the direct-coupled design bring out the finest details of music even more clearly, enabling an unprecedentedly deep sound experience.

Precise Control with Digital ATT

The digital ATT (attenuator) using a long-life relay allows precise gain adjustment in 0.5dB steps. Attenuation is displayed numerically and volume settings are intuitive, making it easy to adjust the ideal volume balance.

SATRI-LINK for every detail of sound

Equipped with SATRI-LINK for current signal input, the ultimate amount of information can be obtained by connecting to Bakoon Products / SCL DACs, phono amplifiers, and preamplifiers. You will rediscover the depth of music.

Perfect speaker control and short delay time

The DF (Damping Factor) of the speaker control is very stable at 72.7, 72.7, and 57.1 at 1W, 5W, and 10W, respectively, for optimal speaker control. In addition, a short delay time of 25ns (nanoseconds) ensures extremely fast signal processing and high speed reproduction.
