Sprout100 is the all-new, heavily-updated replacement for the original PS Audio Sprout. Many improvements have been made including double the output power and a fully redesigned headphone amplifier. Also included are Stereo-RCA analog in/outputs, a DAC that decodes full resolution PCM & DSD, a subwoofer output, and a sleek, brushed aluminum remote control. Sprout100 is identical to the original PS Audio Sprout in many ways as well: size, shape, look and feel. Materials of machined and bead-blasted aluminum. Real walnut. And all the sound quality you have come to expect from PS Audio.

Scott McGowan grew up at the PS Audio factory, sharing his father Paul’s love of music and high-end performance audio. But he disliked the complexity, cost and tangle typical of Audiophile systems. Why couldn’t he have the performance levels of his father’s creations packaged in a single, beautiful product he and his friends could afford to own? It should be powerful yet simple to operate. Its aesthetics should be inspired by the “less, but better” designs of Braun’s Dieter Rams and Apple’s Jony Ive. He would call it Sprout.

Sprout100, the newest edition of the beloved original, is a simple, elegant source of music for those who want quality sound without the hassles that come with it. Appealing to the eye and ear, solid and reassuring to the touch, Sprout’s user interface is human, providing visual and audible feedback to the user and connecting her to the music.

Sprout’s ease of use makes it appealing and accessible to music lovers around the world. It features a phono preamplifier for vinyl, a Bluetooth receiver for music streamed from smartphones, a high-quality hi-res DAC to handle anything stored on a computer, enough power for any speaker, and a headphone amp that drives even the toughest loads.
