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.


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.


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.

If I had to recommend an integrated amp as a starter piece for someone, though, this would be my pick right now. There is room to build a hi-fi system out of it because you can add a subwoofer, you can try out a turntable, or a CD player, or even network streamer. Then, if you want to upgrade to separates later, you can easily move the Sprout100 either into your living room to boost the sound there or into an office and just add some nice bookshelf speakers and continue to enjoy this wonderful piece of hardware. Great sound paired with well-chosen features at a very fair price.


Future Audiophile

Andrew Dewhirst

With the release of its next-generation Sprout100, PS Audio has succeeded in making the tired terms “new and improved” actually mean something by addressing many real-world audio needs. There are upgraded features outside and updated technologies inside. Sonically, you get more headroom, heft, and body, plus greater substance and resolution. Revisiting my review of the original Sprout, I can say that my conclusion still rings true: “The Sprout offers plenty of quality without complication. Just connect the little guy and use the knobs on the front. For simplicity, versatility, portability,…


The Absolute Sound

…the Sprout100 / ELAC Debut 2.0 system is in every respect a winner. While you won’t get everything, where would you put it (thanks, Steven Wright), what you will get is a hifi capable of mating you to your music in meaningful ways. I also find the Sprout to be one heck of a nice looking piece of kit, better looking in fact than the endless parade of black metal box w/silver faceplate clones. Sprout has character, and wood! What more can you ask?
Based on my experience, if you decide to buy the PS Audio Sprout100 and the ELAC Debut 2.0 speakers, I can safely extrapolate from that…


Twittering Machines

Michael Lavorgna

It could welcome new folks to hi-fi and greet them with enough quality to keep them in the freakin’ game. The Sprout100 is certainly hi-fi, and as far as New Record Day is concerned, it’s one of the most thorough examples of what hi-fi should and can be.

It’s a no-brainer. It’s a no-brainer!!


New Record Day

Ron Brenay

The Sprout100 is quite a few steps beyond what you’d get with a $1,000 AVR. It’s just better…. You’re going to be …experiencing sound in a way that’s just going to blow you away. You’re going to be absolutely stunned by how good this thing sounds.


Zero Fidelity

Sean Fowler

So, there you have it. Whereas I found the original Sprout to be important, but not necessarily a complete success, I think PS Audio got things very right with the updated Sprout100. Great sound, great ergonomics, a well thought out feature set that does everything that is important in this price range and does it quite well. And it does it all at a lower price than the original. There’s a reason I gave it a Writer’s Choice award. Very highly recommended.


Positive Feedback

Steve Lefkowicz

It’s obvious a lot of thought, passion, and heart went into the design of the Sprout100. It has been beautifully voiced by some hardcore music lovers. At only $599 (which is cheaper than my USB cable) I consider the Sprout100 to be one of the best-kept secrets in audio. One of those rare times you could steal your cake and eat it too.


Audio Bacon

The Sprout100 seems born to stream music and play vinyl via a low-cost MM cartridge. Its best trait was that it made recordings sound tuneful and attractive. Its worst trait was that it made recordings sound tuneful and attractive. It did not do such audiophile tricks as strong, tight bass, precise imaging, transparency, or airy highs. It just played music enjoyably.



Herb Reichert

Who says really sexy audiophile gear needs to be expensive? This $599 integrated amp is the perfect gateway into our hobby, with modern connectivity and simple operation. You have to start somewhere and $599 isn’t too bad for a component this nice and this well-connected.


Home Theater Review

The brushed aluminum-clad remote control that comes with the Sprout100 is a definite upgrade over the credit-card types you get with some gear. It has a substantial feel when seated in the hand, and its power, mute, and volume up/down control buttons click audibly when pressed. I was happy to see a printed owner’s manual—an endangered species in the A/V world—when I opened the box, especially an informative, clearly written one.


Sound & Vision

I think I have a Sprout100 in my future.

Like many in our generation, I fulfilled my audio needs with receivers….But now, having tried the Sprout100, I’m reconsidering. The Sprout100 isn’t a receiver, but an integrated amplifier in a small size that packs quite a punch. 10.5 inches across, 5 inches high and 14 inches deep, it weighs in at under 3 pounds. But in the aluminum box with a wood veneer top is up to 100 watts of speaker output per channel, more than enough to drive my big floor speakers to room-shaking loudness (I cranked it up when the Mrs. was out on an errand). I’m not an…


Tech 50+

Bill Stoller

The detail and depth are just striking. It’s still the channel separation and imaging that is grabbing me hardest…I’ve never had this disc startle me. I turned around because one of the voices came from behind me. This is two channel that I’m listening to. The Sprout has opened up the soundstage so wide that it played a ventriloquist act. I’ve never had a piece of gear do that in this room. The second track sounds like a drum circle in the room.


The Shoestring Audiophile

Michael Laurance

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.


Home Theater Review

Steven Stone

A Sprout, you say? Indeed, I’m speaking of PS Audio’s gateway drug into high-end audio, the venerable Sprout integrated amplifier/DAC/phono preamp. It seems that receipt of a Sprout has become something of a coming of age moment in my family. My daughter got the first generation sample I reviewed when she was a junior in college, having moved out of the dorms and into a place of her own with a bunch of other collegiate ladies.

…Ultimately, as with the original Sprout, I had to conclude that one of the best attributes of the Sprout 100 is that it serves to bring generations of people…


Part Time Audiophile

John Richardson

I began this review by stating that PS Audio was once considered the poor man’s budget audiophile gear, and the PS Audio Sprout100 continues that tradition without reservation. Providing a large soundstage with excellent dynamics, a great tonal balance and musicality sufficient to tame the occasionally edgy SABRE DAC chip, while able to drive anything from the most sensitive of IEMs to reference quality planar magnetics, the Sprout100 has earned a place as one of my three favorite DAC/Headphone Amplifiers under $1,000, and is only bested by the Modwright/Oppo DAC, as an ESS based DAC.



Headphone Guru

Gary Allen Barker

…to see how the Sprout100 can handle these very serious speakers that cost $15K per pair, with a frequency response down to 29 Hz. We jumped right to it and played Bela Fleck’s classic cut Flight of the Cosmic Hippo. The Sprout100 drove them well, displaying more depth, more bass, more presence and shaking my couch. Of course they did not yield the sound quality that the Celesta shows off with when paired with my 700 W per channel reference mono blocks, and peripheral reference equipment—but confirming that a $599 Sprout100 can drive these speakers was a revelation.

At the mere price of…



Karl Sigman

I pulled out about $6,000 worth of amp and preamp and stuck the $599 Sprout between a pair of Legacy Classic speakers on the output side and about $12,000 worth of MC cartridge, tonearm, turntable, phono cable and phono stage on the input side of the Sprout using the analog input. Not a fair test at all. I was setting up the Sprout to fail. It was surprising easy to listen to. Very non-fatiguing. Not grainy or crappy at all. This $600 unit held its own.

This is the new vintage integrated amp. And with Bluetooth and all those other features this could be the entry level integrated that you…


Record Collector News

Jim Kaplan

The Sprout100 ticks all the boxes and then some. It poses a headscratcher of a question itself: What does it not do for $599? And as you can see from the specs listed below, “not much” is the answer. How one judges PS Audio’s latest incarnation is a matter of perspective, so I’m going to look at it as the core of 3 systems: starter, office, and travel. Normally, specifications find themselves at the end of a piece, but the Sprout100 is nothing short of extraordinary for the price.
