A pure analog amp from a digital heavyweight
Since 2011, Singxer has operated as an ODM and OEM in the audio industry as well as developed their own DACs and digital interfaces. Best known for their work in digital audio, they’ve made technical achievements in clock systems, phase-locked loop technologies, and more. In a bit of a departure for a company that so heavily favors digital products, Singxer has now released the SA-1, a fully balanced pure analog class A amplifier.
Call it beginner’s luck or pure talent: Singxer has knocked this one out of the park. The SA-1 offers superb amplification, vanishingly low noise floor, and nominal distortion. It’s a great choice for anyone looking to graduate to a high-end balanced amplifier that can double as a preamp.
Fully independent Class A analog amplifier
The Singxer SA-1 is a class A pure analog amplifier. Using simple circuits that draw the same amount of current and consume the same amount of energy whether receiving a signal or not, this is the most straightforward of amplifier types. It isn’t subject to electromagnetic interference caused by digital components, so its total harmonic distortion and signal-to-noise ratio are exceptionally low.
Exceptionally clean signal
The Singxer SA-1’s signal-to-noise (SNR) is 126dB. To put that tremendously high number in perspective: the loudness of an ambulance’s siren is 120dB. So you’d have to crank the SA-1 louder than an ambulance before hearing any hiss or other unwanted noise. In any normal, healthy listening scenario, you’re going to hear nothing but pure signal.
Seven inputs and outputs
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.
