Radically simple amplification

The SH-8s is the radically simple new headphone amp from SMSL. Its feature set is slim, its user interface simple. Boasting nothing more than a few toggles and a volume knob, it shines most brightly where the light doesn’t: inside its chassis. Its internal components achieve massive output and ultra-pure noiselessness for a less-is-more experience. There are no bells and whistles, and certainly no snake oil. This is amplification, pure and simple.

6W x 2 of powerful output 

Power your entire headphone arsenal with 6Wx2 of power. 

Ultra low noise

The SH-8s has an ultra-pure signal of 99.99994%, meaning that your music will be free of the harmonic noise and distortion that plagues other amplifiers. 

Gain switch

Toggle the gain switch for a 17.5dB adjustment--perfect for powering a pair of high impedance full-sized headphones.
