SCL AMP-8510A by Bakoon Products A Class Single No Feedback Power Amplifier

High-performance amplifier providing ultimate sound quality experience

AMP-8510A is an innovative semiconductor A-class single feedback amplifier designed to exceed the expectations of music lovers. It is a product full of technology and commitment to push the limits of sound quality.

Selectable semiconductor, infinite sound quality experience

AMP-8510A can choose from the following three types of output semiconductors:

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

MOS-FETs are widely used in audio amplifiers due to their extremely fast and efficient switching. The distinctive advantage of MOS-FET is its high input impedance and low output impedance. This allows MOS-FETs to deliver large currents while minimizing sound quality deterioration.

Three semiconductors, silicon carbide (SiC) and ultra-low-output impedance MOS-FET, each have different sound quality characteristics and are suitable for specific music genres. The following details the characteristics, reputation, evaluation and what kind of music genre is suitable for each.

SiC (silicon carbide)

SiC devices are known for their high switching speed and efficiency. As a result, the sound is very accurate, clear and detailed. High sound range produces clear sound with transparency, middle sound range is clear, bass is less distortion, there is a tight attack feeling.
SiC semiconductors are highly valued for their accuracy and detailed sound quality, and are often used in high-end audio amplifiers. Audio fans support the ability to faithfully reproduce the subtle nuances of music.
Ideal for classical music, jazz, acoustic performance, and other music that emphasizes fine detail. In addition, music with complex instrument composition and wide dynamic range also demonstrates its performance.

Ultra-low output impedance MOS-FET

Ultra-Low Output Impedance The MOS-FET provides a smooth and stable sound quality with extremely low impedance of the output stage. Overall, it has flat frequency characteristics, and the sound from the low to middle range in particular is powerful and clearly reproduced.The warm and smooth sound quality provides a natural medium range and deep rich bass. Low output impedance minimizes signal strength loss, enabling rich and powerful sound. Less distortion,The sound quality is very smooth to high sound range and does not get tired.
Compared to conventional MOS-FETs, it is highly appreciated by audio enthusiasts for its high freshness and stable sound quality. It is especially preferred in amplifiers with a balance of technical precision and musical warmth. In order to provide sound that combines delicate reproduction and smoothness, it is supported by audio fans seeking a relaxed and natural listening experience.
Ideal for genres that require warm, rich sound quality such as blues, soul, and classic rock. It is also suitable for vocal-centric music where natural midtone is important.

Insulated Gate Bipolar Transistor)

The biggest feature is the strong and thick sound. The IGBT structure, which supports high current and high voltage, is directly connected to the amplifier's drive force, and it demonstrates excellent reproducibility, especially in the medium and low range extrusion and energy feeling. In addition, the smooth sound quality per ear is also a big attraction, and you can enjoy rich musical expression that reduces the hardness that tends to be in the transistor amplifier. Compared to MOS-FET, the sound has a strong density, and it tends to be preferred by listeners seeking the thickness and reality of analog sounds.

On the other hand, sound tendency is often tuned with emphasis on smoothness and texture of the entire music, rather than speed and sharpness of high range, and depending on the genre and listening style, it may feel a little calm. For those who value the sharpness of sound and the speed of rise, it may appear a slightly different direction, but it also contributes to the flow of natural sounds that are difficult to hear and tire as a personality of IGBT amplifier.

In general, the IGBT amplifier can be said to be a type of amplifier that firmly depicts the temperature and texture of the music, with a balance of power and smoothness. Compatibility with genres such as classical, jazz and vocals is particularly suitable for listening styles that want to immerse themselves in music deeply.

The four semiconductors above are crystals of semiconductor technology that play an important role in high-performance audio equipment. These technologies are an indispensable element in modern high-end audio equipment, providing a richer and clearer musical experience. The unique characteristics of each semiconductor make it possible to enjoy minute differences in sound quality and realize the ideal sound.

Overwhelming sound quality and high precision

8Ω with 10W output at AMP-8510A load, distortion at 1W is only 0.025%, and frequency characteristics correspond from 10Hz to 100kHz. Furthermore, the sine wave has the phenomenal characteristics of passing through the 1MHz, and the details of the music are breathtakingly vivid.

Overwhelming drive by direct connection design

The biggest feature of the AMP-8510A is the direct connection between the output semiconductor and the speaker without any intervention. This design is not feasible with complementary PP (push pull). The output is 10W and the bias current is 1.8A, and due to the characteristics of class A single, more bias current is required. With this direct design,Even with SATRI-LINK connections through current signal transmission, minute nuances of previously audible sounds are now clearly replayed. Thanks to the direct design, the detailed details of the music come up more vividly, allowing you to experience a deeper sound than ever before.

Precise control with digital ATT

Digital ATT (Attenuator) with long-life relay enables precise gain adjustment in 0.5dB steps. You can easily adjust the ideal volume balance by displaying the decrease in numbers and intuitively setting the volume.

SATRI-LINK

The SATRI-LINK of the current signal input is installed, and the ultimate amount of information can be obtained by connecting with Bakoon Products/SCL DAC, phono amplifier, preamplifier, etc. You can rediscover the depth of music.

Perfect speaker control and short delay time

The speaker-controlled DF (dumping factor) is very stable at 1W, 5W, and 10W respectively at 72.7, 72.7, 57.1, and controls the speaker optimally. In addition, the short delay time of 25ns (nanosecond) enables very fast signal processing and high-speed regeneration.
