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. \u003cbr\u003e\u003c\/p\u003e\n \u003cp dir=\"ltr\"\u003eCall 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. \u003c\/p\u003e\n \u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eFully independent Class A analog amplifier\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp dir=\"ltr\"\u003eThe 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. \u003c\/p\u003e\n \u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eSeven inputs and outputs\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp dir=\"ltr\"\u003eThe 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. \u003c\/p\u003e\n \u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eFully independent class A analog amp\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eSuper clean output with low distortion and low noise floor\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eSeven inputs and outputs\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eFully balanced architecture\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eHeadphone amplifier and preamplifier\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eAmplification type: Class A\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eTwo gain modes: low\/ high\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eInputs: Balanced XLR, RCA\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eOutputs: Balanced XLR, RCA, Balanced 4.4mm, Balanced 4-pin XLR 4, Single-ended 6.35mm\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eSNR: 126dB\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eDynamic range: 147dB @A-wt\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eTHD+N: \u003c\/li\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"2\"\u003e0.000078% @balanced input and no output load\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"2\"\u003e0.000128% @balanced input and 33Ω output load\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eNoise level: \u003c\/li\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"2\"\u003e0.66µV @ Max output, SNR \/ DNR 147dB\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"2\"\u003e300nV RMS @ Low gain, A-Weighting, 20Hz-22kHz\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eOutput power\u003c\/li\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"2\"\u003e6480mW @ 32Ω\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"2\"\u003e2000mW @ 120Ω\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"2\"\u003e380mW @ 600Ω\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003ePower supply: 100-240V AC, 50\/60Hz\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eDimensions: 9.2 x 6.6 x 1.8” (234 x 170 x 46mm)\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eHousing material: Aluminum\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eColor: Black\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003eWeight: 3.9lbs (1.8kg)\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eWhat’s included\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e1x Singxer SA-1\u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e1x Power cable\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\n \u003cstrong\u003e Featured\u003c\/strong\u003e \u003cstrong\u003eReviews\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h3\u003e\n \u003cp\u003e\u003c!-- split --\u003e\u003c\/p\u003e\n \u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/yoOPau-fNho\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" width=\"560\" height=\"315\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n \u003cstyle type=\"text\/css\"\u003e\u003c!--\n td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}\n --\u003e\u003c\/style\u003e\n \u003cp\u003e\u003cem\u003e\"I don't want to listen on any other amplifier right now.
