SMSL (Foshan ShuangMuSanLin Electronics) is a Chinese audio-electronics maker founded in 2009 that builds desktop DACs, headphone amps and class-D speaker amplifiers, widely known for measurement-forum-favourite performance at low prices.

A flagship-chip DAC at half the flagship price — and the usual argument over whether you can hear the chip at all.

The cheapest way to stop worrying about your DAC — as long as yours is one of the ones that keeps working.

Measured beyond reproach and argued about anyway — over whether it has a sound, and over what that 4.4 mm jack is really wired to.

A top-twenty measuring DAC for $250 that adds nothing of its own — which is either the whole point or the whole problem.

SMSL's matched DAC-and-amp desk stack measures like far pricier gear — what reviewers actually argue over isn't the sound, it's one clicky quirk.
