As PS Audio's newest, first-tier integrated amplifier, Sprout100 represents our vision of a simple, elegant means of playing music at home.

Sprout represents our vision of a simple, elegant means of playing music at home. We created it for those of us who want quality sound without the hassles that sometimes come with it. Sprout 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. Roughly the size of a large novel, Sprout100 is a source of music for those who want quality sound without the hassles that come with it.

Design

Designed to be compact and elegantly versatile, Sprout100 brings the content of yesterday to the technology of today. Sprout100 offers a maximum-resolution DAC, a variable subwoofer mono output, full RCA analog in/out connectors, a world-class RIAA phono-stage, a z-feedback low impedance headphone amplifier, and a universal internal power supply that allows you to take your new integrated amplifier abroad for maximum flexibility. Adorned with real walnut and machined aluminum knobs, each and every Sprout100 is unique.

Application

Sprout100's ease of use makes it appealing and accessible to those who would find most audio gear intimidating. Sonically notable for its lucid spatial detail, acute tonal retrieval, and commanding noise immunity, Sprout100 is equipped to drive your loudspeakers and headphones better than ever. For those seeking a better, simpler way to play music in their home, Sprout100 will fill your living room, bedroom, or any room with enormous, live sound. Sprout100 provides quality without complication.

Technology

Sprout is a simple, elegant source of music for those who want quality sound without the hassles that come with it. Sprout was designed by PS Audio's Scott McGowan as an answer to the complexity and cost of Audiophile systems. Appealing to the eye and ear, solid and reassuring to the touch, 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.

Inputs

To ensure the best possible vinyl reproduction, we engineered a brand-new hybrid circuit design that incorporates a JFET input stage, to lower noise and increase headroom, and a passive high-frequency RIAA circuit, for extended and nuanced high-frequency response. Optimized to the cutting edge of digital playback, Sprout100 also employs an ultra high-resolution ESS Sabre DAC (9016) with USB-B input that accepts resolutions up to PCM 384/24 and DSD128: bit-perfect playback for your high-rez computer audio, video, and gamin applications. An optical (toslink) input allows you to incorporate a TV or other modern digital device with your new system. Bluetooth offers versatility, convenience, and one-touch access to a world of content.

Power

Equiped with bleeding-edge ICEpower amplifier technology, the Sprout100 offers 100 watts per channel, with peaks of up to 135 watts per channel. The Sprout100 also features a built-in subwoofer output (mono RCA, variable), allowing you all the rumble you want with the powered subwoofer of your choosing. With one of the finest headphone amplifiers made, the Sprout100 honors and respects the music with a low-impendance z-feedback circuit that is capable of driving virtually any pair of headphones you can throw at it with perfect transient impulse response. Slewing at an unheard of 1,300-volts/microsecond, the Sprout100's headphone amp produces lucid spatial detail and acute tonal retrieval.
