For headphones in need of classic analog amplification with modern performance, the SA-1 balanced headphone amp from Singxer is a class-leading fit. Equipped with Singxer's own custom, four-way fully discrete Class A amplifier circuit, the SA-1 is all analog—from the internals all the way to the controls. This pure analog design delivers warm and expressive amplification devoid of any EMI interference caused by digital components, making the SA-1 loud, and quiet, in all the right ways. With an impressive signal-to-noise ratio of 126 decibels, it won't be sending your ears anything but pure signal. And with XLR and RCA inputs alongside a wide range of outputs—including 4-pin XLR, 4.4-millimeter balanced, and 6.35-millimeter single-ended options—it's capable of handling preamp or headphone amp duties in virtually any setup.
