The Soncoz SGP1 is a massive Class AB amplifier, designed for integration into high-resolution audio systems, which the brand has been working on for three years. In addition to comfortable power, it provides excellent SNR and THD, offering a whole new level of performance in the world of discrete Class AB amplifiers. Each parallel NPN/PNP channel with push-pull output allows the SGP1 to accompany demanding loudspeakers in a more comfortable way. The SGP1 is also a model that reveals a beautiful musical expression, with deep bass and clear high frequencies.

Reference performance

High audio resolution is intrinsically linked to low noise and distortion. Thus, the brand has done some real design work to achieve excellent measurements. The SGP1 offers an SNR of 130dB at its maximum output level (A-Weighted), making it 15 to 30dB quieter than many of today's high-end amplifiers.

Custom power supply circuit

For the SGP1, Soncoz paid great attention to the power supply stage, so that it is able to provide the large amount of power needed to operate the amplifier modules. This allows the SGP1 to provide immediate and continuous power output. After the AC input, the SGP1 is equipped with two four large 2700µF 200V capacitors, which effectively suppress power supply interference and noise and thus provide a clean electrical signal for all audio circuits.

No heating required

Unlike most Class AB power amplifiers, the SGP1 reaches its maximum performance in less than a minute. Therefore, there is no need to leave the unit on when not in use. In addition, the SGP1's driver module ensures high stability over a wide temperature range.
