Soncoz has just announced its latest fully balanced headphone amplifier and pre-amplifier, the all-new Soncoz SGA1. Matching the design of their flagship SGD1 balanced DAC, the SGA1 is the perfect companion for SGD1 to complete a fully balanced desktop headphone amplifier and pre-amplifier stack. It features a fully balanced architecture with XLR for signal input/output, with 4-pin XLR and 4.4mm balanced headphone output. It also has RCA for single-ended input/output and a 6.35mm single-ended headphone output port. Soncoz SGA1 balanced HPA and Pre-AMP is launched for 649.99$.

Flagship Amplifier Made For Flagship DAC:-

Soncoz has designed their flagship SGA1 amplifier matching their flagship SGD1 DAC. Both the devices are simply made for each other matching both in terms of looks, dimensions and have an excellent compatiblity with each other. With both the SGD1 and SGA1, you can create magic with a fully-balanced headphone amplifier and pre-amplifier.

Ultra-Low-Noise OP-AMPs:-

Soncoz has designed the SGA1 with carefully selected high-performance Operational-Amplifiers. The amplifier features multiple units of OPA1611, OPA1641, OPA1622, and more to ensure an outstanding performance with the Soncoz SGA1. Among these, RCA and XLR analog input buffers use 4 OPA1661s, electronic output butter uses 2 OPA1641s, Pre-output buffer uses 4 OPA1611s, and HPA output buffer uses 4 OPA1622s. You are provided with nothing else but high-quality sound output for your High-Resolution headphones.

Multi-Function Knob:-

The volume knob on the SGA1 is not just your regular volume knob. it also has a button underneath that you can use to access various functions on the SGA1 including Mute, Standby, Volume/Gain mode switch, and many more. It makes it extremely easy to control various functions on the SGA1 with this Knob.

Precise Volume and Gain Adjustment With Memory Function:-

Soncoz SGA1 integrates MUSES72320 high-performance electronic volume adjustment resistance ladder circuit for precise volume and gain adjustment with low noise and low distortion in the output. It has 0.25dB/step volume increase when gain=0, and 0.5/dB when gain is not 0. Adjustment range of Volume is -110.75dB~0dB. Gain adjustment is 0.5dB/step with an adjustment range of -6dB~0dB for HPA and -7dB~0dB for Pre-AMP. Your Soncoz SGA1 also memorizes your settings for each input and output option. So you don’t have to worry about adjusting your volume settings everytime you switch the input mode. It also remembers your settings even when it is powered off.

Audiophile-Grade Performance With High-Quality Components:-

Soncoz has designed SGA1 with high-quality components to ensure high-quality performance. The rectifier circuits of SGA1 use two large capacity(8200uF*2) ELNA audio capacitors to ensure the ultra-low ripple voltage of the main power supply. In the key audio signal path, SGA1 uses WIMA MKS2 series non-polar film coupling capacitors that greatly improve the quality of the audio signal. For ultra-clean power, the Soncoz SGA1 is features a custom toroidal transformer containing multiple layers of permalloy shielding. The 50/60Hz power frequency noise and its harmonics are significantly reduced providing clean, distortion-free power to the different components on the circuit.
