PS Audio Sprout100
All New Features, Same Great Story
Sprout represents PS Audio’s vision of a simple, elegant means of playing music at home.
Sprout offers sonic ideals and design principles enjoyed by many thousands of users daily.
Its ease of use should make it appealing and accessible to those who would find most audio gear intimidating; it should also appeal to those who have “been there, done that” and seek a better, simpler way to play music in their home.
It is in this spirit of passion and technological advancement that PS Audio proudly announces our newest, first-tier integrated amplifier: Sprout100
Sprout’s design principles will never change: compact, elegant versatility that brings the content of yesterday to the technology of today. Sprout’s performance and features have been overhauled: more power, more resolution, more romance.
How is Sprout100 different from the original?
To start, Sprout100 offers double the output power, which—apart from providing renewed efficiency, lowered distortion, and greater separation and detail—also serves to galvanise the sonic benefits of extended headroom.
Sprout100 offers a DAC with maximum resolution—one that decodes even 128DSD and 384/24PCM.
They heard you wanted a remote control, an indicator light, a defeatable bass-boost, and an optical input? It’s all there.
Sprout100 also differs from the original by offering a variable subwoofer mono output, full RCA analog in/out connectors, a redesigned world-class RIAA phono-stage, and a newly designed z-feedback low-impedance headphone amplifier. And with Sprout100’s universal internal power supply (100 – 240VAC @ 50/60Hz with auto-detect) you can take your new integrated amplifier abroad for maximum flexibility.
By adapting new high-resolution/low-distortion topologies, a beefy 240-watt power supply, and bleeding-edge ICEpower amplifier technology, Sprout100 offers increased headroom, lower noise floor, and extended and nuanced frequency response. Z-feedback innovations reveal temporal accuracy and increased transient impulse response.
Sonically notable for its lucid spatial detail, acute tonal retrieval, and commanding noise immunity, Sprout100 is even more equipped to drive your loudspeakers and headphones than before.
But many things didn’t change. For example, the size, feel, shape and style are the same. Like its predecessor, Sprout100 is adorned with real walnut and machined aluminum knobs—making each and every Sprout100 unique.
Their attention to detail is the same. Their passion remains true. Their philosophy will never change
