SCL AMP-8510A by Bakoon Products Class A Single Non-Feedback Power Amplifier

High-performance amplifiers for the ultimate sound quality experience

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

Semiconductors to choose from, endless sound quality experience

The AMP-8510A is available in four output semiconductor types:

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

MOS-FETs are widely used in audio amplifiers due to their extremely fast and efficient switching capabilities. The distinctive advantages of MOS-FETs lie in their high input impedance and low output impedance. This allows the MOS-FET to deliver large currents with minimal degradation in sound quality.

The 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 music genres. Below we will detail the characteristics of each of them, their reputation, their ratings, and what musical genres they are suitable for.

SiC (Silicon Carbide)

Sound Quality Features: SiC devices are known for their fast switching speed and high efficiency. As a result, the sound is very accurate, with clear and detailed sound quality. The treble produces a clear sound with a sense of transparency, the midrange is also clear, and the bass has little distortion and a tight sense of attack.
Evaluation: SiC semiconductors are highly regarded for their accuracy and detailed sound quality, and are often used in high-end audio amplifiers. Audiophiles favor its ability to faithfully reproduce the subtle nuances of music.
Best Music Genres: It's ideal for classical, jazz, acoustic performances, and other music where fine details are important. It also performs well in songs with complex instrumentation 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 a very good transient response, very fast switching capability and efficient power transmission for dynamic and powerful sound quality. It has a good rise and response of sound, and is characterized by an energetic and vivid sound.
Evaluation: GaN-FET technology is attracting attention as a next-generation semiconductor material in the audio industry.It is considered to be state-of-the-art and is especially popular with users who are looking for a highly efficient and powerful sound. Compared to conventional silicon transistors, it is considered a step ahead in terms of energy efficiency and sound accuracy.It is especially appreciated in amplifiers where efficiency and performance are critical.
Best Music Genres: It is ideal for rock, electronic music, pop, and other genres that require dynamic range and energy. It excels in contemporary music that calls for punchy bass and crisp highs.

Ultra-low output impedance MOS-FETs

Sound Quality Features: Ultra-low output impedance MOS-FETs have an extremely low impedance of the output stage, which allows the speaker to drive very well, providing smooth and stable sound quality. It has an overall flat frequency response, and the sound is reproduced powerfully and clearly, especially in the low to mid range.It has a warm and smooth sound quality that delivers natural midranges and deep, rich bass. The low output impedance minimizes the loss of signal strength, resulting in a rich, powerful sound. Less distortion,It is characterized by a sound quality that is very smooth and does not get tired of listening to the high frequencies.
Evaluation: Compared to conventional MOS-FETs, the sound is even fresher and provides more stable sound quality, which is why it is highly regarded among audiophiles. It is especially preferred in amplifiers that strike a balance between technical precision and musical warmth. It offers a sound that combines delicate reproduction and smoothness, making it a favorite for audiophiles looking for a relaxed and natural listening experience.
Best Music Genres: It is ideal for blues, soul, classic rock, and other genres that require warm and rich sound quality. It is also suitable for vocal-centric music where natural midranges are important.

The above four types of semiconductors are the crystallization of semiconductor technology that plays an important role in high-performance audio equipment. These technologies have become an integral part of modern high-end audio equipment, providing a richer and clearer music experience. Due to the unique characteristics of each semiconductor, you can enjoy the subtle differences in sound quality and achieve the ideal sound.

Unparalleled sound quality and high accuracy

With an output of 10W into an 8Ω load, the AMP-8510A delivers only 0.025% distortion at 1W and a frequency response from 10Hz to 100kHz. In addition, it has the incredible ability to pass up to 1 MHz in a sine wave, which makes the details of the music breathtakingly vivid.

Overwhelming driving force due to direct connection design

The biggest feature of the AMP-8510A is that the output semiconductor and the speaker are directly connected without any intermediary between them. This is a design that is not feasible with complementary PP (push-pull). With an output of 10 W and a bias current of 1.8 A, a large bias current is required due to the characteristics of a Class A single. With this direct connection design,Even with the SATRI-LINK connection via current signal transmission, minute nuances of sound that were previously inaudible can now be clearly reproduced. Thanks to the direct-to-door design, the fine details of the music stand out even more vividly, allowing for a deeper sound experience than ever before.

Precise control with digital ATT

A digital attenuator (ATT) using a long-life relay allows precise gain adjustment in 0.5 dB steps. The attenuation amount is displayed numerically, and the volume can be set intuitively, so the ideal volume balance can be easily adjusted.

Every detail of sound with SATRI-LINK

Equipped with SATRI-LINK for current signal input, it can be connected to Bakoon Products/SCL DACs, phono amplifiers, preamplifiers, etc. to obtain the ultimate amount of information. You'll be able to rediscover the depth of music.

Perfect speaker control and short lag times

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