Compact, No-Fuss, Hi-Fi Link Between Your Music and Speakers or 'Phones Features Sabre DAC: 100Wpc PS Audio Sprout100 Integrated Amplifier Plays Vinyl, 2x DSD, Bluetooth, Discs, More

No bigger than a hardcover novel and able to handle both analog and digital with incredible prowess, the newly enhanced PS Audio Sprout100 integrated amplifier will change how – and where – you listen. Equipped with just two machined-aluminum knobs – one to select your source, one to crank it up – Sprout100 is the no-fuss link between your favorite music and speakers or headphones. Able to play soul-rejuvenating music from any turntable, computer (via USB), DVD or CD player, Bluetooth-enabled device, tuner, or gaming console, The Absolute Sound Product of the Year Award-winning Sprout100 only requires a pair of loudspeakers or headphones. Then, stand back, and enjoy the room-filling high-fidelity sound remarkable for its spaciousness, detail, tonality, and dynamics. The high-res-capable and walnut-panel-adorned Sprout100 remains ready whenever – and wherever – you are. And it arrives loaded with serious high-end audio components and capability.

Offering the double the power of its Product of the Year Award-winning predecessor, Sprout100 adds a redesigned RIAA phono preamplifier, 240-watt power supply, and a fully asynchronous Sabre 9016 DAC that handles up to 2x DSD and 24-bit/384kHz. Its re-engineered amplifier pumps out a powerful 50Wpc into eight ohms and 100Wpc into four ohms. Lower noise levels complement upgraded dynamic capabilities and linearity, while the presence of cutting-edge ICEpower modules contribute to the impactful, clear, and involving sonic presentation marked by a very low noise floor, extended frequency response, and delicious headroom. A discrete z-feedback low-impedance headphone amplifier, variable mono subwoofer output, handheld remote control, optional bass boost, analog RCA inputs and outputs, and TOSLINK optical input round out a Swiss Army knife of a high-end component that is simply without peer. 100% Music Direct Satisfaction Guaranteed.

While I never voiced them in print, I had some reservations about the original Sprout due to its always-on loudness curve and lower-than-I-usually-need power output capabilities. The new Sprout100 eliminates both of those concerns. Not only does it sound amazingly good, but it has enough of the right inputs and outputs to put together a first-rate, borderline drop-dead kick-ass desktop or even room-based audio system.”
—Steven Stone, HomeTheaterReview

“This $599 integrated amp is the perfect gateway into our hobby, with modern connectivity and simply operation.”

Passive EQ MM Phono Preamplifier

Sprout100 offers a high-quality phono preamplifier designed to bring your favorite vinyl to life. A brand-new hybrid circuit, JFET input stage for lower noise and increased headroom, and passive high-frequency RIAA circuit for extended and nuanced high-frequency response are among the features that make the MM design tailored for terrific analog performance.

A Plethora of Digital Options Extend to Streaming from Your Phone
To spoil you with high-res playback options, Sprout100 employs an ultra high-res ESS Sabre DAC with USB-B input that accepts resolutions up to 2x DSD (DSD128) and 24-bit/384kHz and delivers bit-perfect playback for computer audio, video, and gaming applications. An optical Toslink input allows you to incorporate a TV or other modern digital device. Bluetooth offers versatility, convenience, and one-touch access to a world of content.

Hand-Selected Power Amplifier
ICEpower amplifier technology equips Sprout100 with 100WPC RMS (peaks of up to 135WPC). This increase in output wattage–apart from providing renewed efficiency, lowered distortion, and greater separation and detail–also serves to galvanize the sonic benefits of extended headroom. Selected for its musical virtues, PS Audio engineer Scott McGowan curated the Scandinavian-designed amplifier from among a dozen fine candidates before selecting it.

Connect to Practically Anything, Even Add a Subwoofer
Upgraded from a pair of 3.5mm jacks, Sprout100’s analog inputs exhibit stereo RCA connections that serve to welcome legacy devices like classic video game consoles or an open-reel tape deck. If you so choose, preamp Sprout100 to your external amplifier. Sprout100 also boasts a built-in subwoofer output (mono RCA, variable).

Discrete Zero-Impedance Headphone Amplifier with an Exceptional Slew Rate
Conventional headphone amplifiers focus on lowering output impedance at the expense of temporal accuracy. To solve this problem, PS Audio engineered a new low-impedance Z feedback circuit to drive virtually any pair of headphones with exceptional transient impulse response. Slew rate, the ability of an amplifier to reproduce transient musical information, is critical to the lifelike presentation of sound. The human ear reacts instantly to temporal shift. We rely on this sensitivity to realize our setting and the movements around us. Paying keen attention to phase shift and temporal accuracy, Sprout100’s headphone amp slews at 1,300-volts/microsecond–100 times faster than that of its predecessor–producing lucid spatial detail and acute tonal retrieval. The same Z feedback topology that delivers stunning clarity also enables commanding noise immunity.

You Also Get a Remote Control
Sprout100 keeps the positive feel of its two, machined, front panel controls while adding the convenience of a beautiful remote control that comfortably fits in the palm of your hand.
