About this project

STRETCH GOAL ANNOUNCED! Let's put one of these custom Sprout Power Boost cables in every box!

Help us get to $425,000 and EVERY box gets a PS Audio Sprout custom designed power cable, which is an $89.99 value. Will you tell ONE friend about Sprout?

PS Audio has been making power cables for fifteen years, and we know the great impact they have on sound quality. The Sprout Power Boost Cable boasts unique stranding, geometry, and shielding, and these crucial differences translate into better performance, enhanced noise rejection, and more powerful dynamics. Exchange any stock power cord with a Power Boost custom designed power cable, and you'll hear it immediately. PS Audio Power Cables tout specially machined prongs, hewn from a solid billet of material. Cold and hot welding, over-molded and hermetically sealed connectors, excellent shielding, and finely stranded spirally wound conductors complete this seriously good cable design. This power cable is the perfect compliment for your hi-end Sprout. 

OK, back to Sprout...

An amplifier for the modern home  

Sprout is the link between your music and your speakers. Sprout is the size of a big novel, yet it will fill your living room, bedroom or any room with enormous, live sound. Sprout is designed down to the very atom. Constructed of stainless steel, extruded aluminum, and walnut, this is not audio equipment. It's audio furniture.

All Music (Connect to Sprout with):

  • Any bluetooth enabled device: tablet, phone, or computer
  • Turntable to play vinyl records
  • TV or gaming console, or even a reel-to-reel tape deck
  • Computer through USB (Hi-Rez)
  • CD or DVD player over COAX

All Speakers (Listen to Sprout with):

  • Any Size Speakers
  • All Headphones

Most likely, you love music

Me too. I'm Scott McGowan. 31-year-old audio-enthusiast, concert-goer, and amplifier-designer. I work at PS Audio in Boulder, Colorado. I've been around HiFi systems my entire life because I love LIVE music. 

Unfortunately, when I play music on my small stereo at home, it just doesn't sound live. But all that has changed.

Home audio can be done better

PS Audio makes high-end stereo systems for audiophiles. An audiophile's goal is to reproduce live music exactly as it is heard on stage. Can that actually be done?

You bet. Our company does it every day.

It's not something most of us can afford however. It's not something most of us have space for either.

Teresa (my fiancee, above) and I have a one-bedroom apartment; we spend our money on bills. Normal-people stuff like student loans and groceries.  We're planning a wedding, not a HiFi system!

Yet who doesn't want concert-quality music in their living room?  From our phones, turntables, computers or CD players: here's how most people listen to music...

These really frustrate me:

And the back is even worse...

Ever notice how these big receivers get tucked away behind cabinet doors?  Ever notice how 90% of their features go un-used?  Worst of all, they DO NOT honor the music.

Loving music should be easy!

What we've invented will change forever the way you listen to music at home, from the lowest quality downloads to the highest quality discs to your best LP's. If you love music like I do, Sprout will change your life and your relationship to music.

Sprout brings me the music: pure, sweet, simple and LIVE!

This is much easier:

And it's all relevant to music lovers.  Nothing superfluous.

Here's the thing...

Stereo equipment is incredibly complicated.  It's a fact.

But then again, so is your car's 4-stroke internal combustion engine.  I have only the vaguest conception of how cars operate.  But I don't have to know.  I drive everyday.  They make it easy.

This is what I want to bring to the home audio industry, which until now has failed normal people like you and me.  Everyone loves music.  But wattage, voltage, signal-to-noise ratio, interconnects, EQ controls, output impedance?  I feel your pain.  Don't get discouraged.

Change has arrived

This is me at the HiFi Show in Munich, Germany (May 2014)

Sprout is the culmination of PS Audio's 42 years' experience building concert quality audio products. We hand selected the best parts of that rich history and put it into a single, simple, easy-to-use personal music system. It's everything you need. Nothing you don't. Just add speakers or headphones, and music—so close to live—will fill your whole home. It's nothing short of magical.

Sprout is designed by music lovers, for music lovers.

Sprout is high definition, playing the purest quality files up to 192kHz/24-bit (trust me, that's a good thing).  

Sprout takes you back to the music's source in a warm, friendly sort of way.  No remote control, just a solid connection between you and your music.  Feel the precision.  Put the tactile beauty of control back in your hands. Reach out for Sprout!

Dock Owners

Add headphones or speakers to Sprout, and your music will come alive. You can adios the dock. 

Receiver Owners

It's big, awkward, and hard to use.  You shouldn't need a degree in electrical engineering to love music in your home.  Sprout is simple and elegant and brings the artists into your living room!

Laptop or Phone Listeners

You've got a great source—unleash it on Sprout, and you'll hear your music for the first time.

Vinyl Lover?

42 years ago PS Audio released our first product: a phono-stage amplifier.  We've been doing it ever since.  We cherish our LP's. Use Sprout to draw every drop of analog purity from your records.

UPDATE: Sprout powers HUGE speakers:

Every Sprout comes with this adapter:

Bottom Line

Sprout delivers.  Concert-quality audio in your home?  That's pretty remarkable if you think about it.  Yo Yo Ma's strings should sound like a cello.  You should be able to distinguish Simon from Garfunkel.  My dad and I are insatiable sound hounds.  We believe the pursuit of live sound is a journey, not a destination.  

You should join us.  It's going to be fun.

Don't miss this chance to own Sprout!

There will never be a better opportunity to bring Sprout home. Help me bring music and magic into the world.

Sprout will retail for $799.99 when it's finished. This is your only chance to score the amazing Sprout personal music system at a very low price and fill your home with the sound of live music like you've never experienced before!

Thanks for listening.

Read what the press says about the Sprout project:

Malcolm Steward, Top Audio Gear: "I want Sprout in my desktop system: it has a performance that allows it to compete easily with the best of the rest, along with the facilities one truly needs in such a product, and is also stunningly attractive – along with being beautifully crafted."

Jaap Veenstra, Alpha Audio Magazine: "Sprout is a refreshing and seriously interesting product for a new generation. It’s easy to use, (very) well built and ridiculously complete. And by complete we mean: USB, phono, line-in, headphone-out, built in amp and much more. And to top it off: it’s well priced!”

Dr. Panagiotis Karavitis, PartTime Audiophile: "PS Audio presented in Munich the Sprout, what could be the most interesting and affordable new product of the entire show. At $799 you cannot ask for more.

     "This little Swiss army knife will stream music from your phone, drive your cans and the speakers on your desktop. The Bluetooth connection was lighting fast; it took Scott less than 20 seconds to bridge it to his iPhone. The built-in DAC sounded very nice with Audeze’s LCD 2 headphones; in fact, after a couple of tracks ('Missed the Boat' from Modest Mouse, 'Audiophile Recordings' and Gluck’s 'Dance of the blessed spirits' from Naxos), all I can say is that it will sell like hotcakes."

Matej Isak, Mono Stereo"Sprout is the brainchild of Scott McGowan, PS Audio’s Sales Director, and son of Paul McGowan. Designed as the simple but high-quality hub of a home music system, Sprout is a 50 watt/channel integrated amplifier that can play music directly from a turntable, any digital input, and wirelessly from a smartphone."

Mark Rushton, StereoNet: "Sprout certainly has an impressive feature-set, and if PS Audio's reputable name is even remotely attached to this off-shoot, one could assume it will be of considerable quality."

...and what the press says about PS Audio:

John Darko, DigitalAudioReview.net: "PS Audio ensures you're looked after each step of the way: the packaging, customer support, website, YouTube channel and firmware upgrades are solid examples of this manufacturer’s innovative ambition." (PerfectWave DAC)

Marja & Henk, 6moons.com: "We firmly believe that we can now speak of the beginning of the second digital revolution... Kudos to PS Audio for being at the very front lines staking out this exciting future." (PerfectWave Transport & DAC)

Anthony Cordesman, The Absolute Sound: "PS Audio’s NuWave Phono Converter is truly an innovative product with great sound and value for the money. A real pleasure to review...." (NuWave Phono Converter)

Karl Sigman, Audiophilia.com: "PS Audio has perhaps achieved the impossible with the DS [DirectStream]. The DS gets my highest recommendation; hats off and a bow to PS Audio." (DirectStream DAC, winner of Publisher's 'Star Component' award).

Risks and challenges

Risk is low. Our track record of designing, building and delivering stereo equipment to music lovers the world over, for the last 42 years, speaks to our tenacity and dedication. This is not our first rodeo!

Pre-production prototypes have been built and the product is fully engineered. We are working on Round II and adding small changes from user feedback to finalize the design. You will get the latest & greatest!

We are doing the Kickstarter program to fund the tooling costs of ramping up production, as well as the large inventory costs associated with building this product and keeping the costs where we need them to be.

We should be able to begin shipping in September, 2014, following a successful Kickstarter campaign.

  • All music must be amplified. Anytime you've ever heard headphones or speakers playing music, there was an amplifier somewhere in the mix. Sprout is an amplifier. A really COOL one. So plug in any speakers or any headphones, and you will have the music.

    Last updated:
  • Yes. There are some speakers out there which are massive, and some speakers out there which are very inefficient, and so you may rule out some speakers that cost $100,000+ but for EVERY speaker out there in the normal range, Sprout will play them beautifully. Sprout is loud and clear and sweet. It is a small box with a huge sound!

    Last updated:
  • Sprout will power any headphones up to and including and even beyond 600ohms. It is a very powerful, very beautiful sounding headphone amplifier.

    Last updated:
  • Sprout is optimized to support moving magnet cartridges. If you have no idea what I am talking about, that's OK, it means your turntable WILL work with Sprout.
