Singxer SA-1 hosts a true four-way fully independent, fully discrete Class A amplifier circuit design with a pure analog amplifier circuit and pure analog control. This eliminates EMI (Electro-Magnetic Interference) interference caused by digital control, to faithfully restore the original flavour of your music. The SA-1 offers superb amplification, surprisingly low noise floor, and minimal distortion. It’s a great choice for anyone looking to move to a high-end balanced amplifier that can double as a preamp.



The amplifier circuit in the Singxer SA-1 adopts the class AB architecture developed by the engineers at the company. The differential input transistor adopts ROHM's ultra-low noise audio dedicated transistor. The transistors are purchased in large quantities and then selected by manual precision matching to ensure the consistency of the differential transistor. For other transistors, we use SMD twin transistors with excellent consistency to ensure better performance. The final output circuit uses multi-stage current amplification, similar to the architecture of a high-power amplifier. Each channel uses 2 pairs of ON Semiconductor's 4A mid-power transistor to output in parallel to ensure low enough internal resistance and strong driving force; it can be done calmly even in large dynamics.



The Singxer SA-1 chipset features high-quality components that enable the device to provide a clean output with ultra-low harmonic distortion and noise. The output has a THD+N rating of -120dB @ 1kHz A-weighting. The output has a super-low noise floor. At low gain, the bottom noise is 300nv RMS A weighted and at maximum output, SNR and DNR are 147db. Even with sensitive pairs of IEMs and Headphones, there is no sign of distortion or noise. All you get is a dark background where the minutest of musical details pop out making the output full of life.



The Singxer SA-1 can be used as a headphone amplifier or preamplifier. As a headphone amplifier, it supports balanced XLR input, RCA input on the back panel, and three outputs on the front panel: 4-pin balanced XLR, balanced 4.4, and single-ended 6.35. As a preamplifier, it supports balanced XLR input, RCA input, and two outputs: balanced XLR and RCA.



Singxer has designed the internal audio circuit of the SA-1 to protect against electrical issues like overcurrent, overload, overheating, short circuit, start-up delay, and more. So users can enjoy their music without worrying about power causing any trouble to the device and enjoy stable operation.

Singxer sa1

A hyped product by some youtubers paved the way to this amp purchase which by no means is a bad product but didn't get me excited. The amp volume has to be cranked up to get some excitement running through you ie. Almost 5 o clock position on the knob and that too on high gain.Ran it for 50hrs on Aunex8 dac ,now will hav to try t out on Topping D90SE .
