Sprout100 Integrated Amplifier

Product Description

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 galvanize the sonic benefits of extended headroom.

Sprout100 offers a DAC with maximum resolution—one that decodes even 128DSD and 384/24PCM. We hear you want 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. Our attention to detail is the same. Our passion remains true. Our philosophy will never change.

Home Theater Review

Steven Stone

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.

The bottom-line question, of course, is whether or not the PS Audio Sprout100 is a good value.

In that regard, I say yes. Hell, yes.

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 together, which is something that seems to rarely happen today. I invited my son to come up to listen and experiment with it to see if he would be interested in having one in his apartment. What began as a simple demo session evolved into a deep discussion of music between father and son; one of those rare moments when two generations find themselves on the same wavelength.

All I can say is that PS Audio has only improved upon what I consider to be its best product ever, and that’s great news indeed for listeners both new and old. Enjoy!

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 hang on to for a long time while you upgrade the components around it. And yes, my son is taking the Sprout with him when he leaves for college this fall. I know I will miss you.

You too son.

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.

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.

The addition of a phono stage and the ICEpower amplifier make it an unparalleled value. In fact, if someone were to come to me and say they had a $5,000 budget to put together a home audio system, I would tell them to spend $1,500 on headphones, $1,500 on speakers, $1,000 on a turntable, then buy the Sprout100 to run it and spend the rest on cables (though it might be a challenge to find $1,500 speakers to match the performance of the PS Audio).

...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 $599, the new and improved Sprout100 Integrated Amplifier excels at all it tries to do; I am hard pressed to find anything wrong with it. A must for those wishing to have a full simple system with fine sound and low cost, it will pair well with just about anything you attach it to, and it only weighs 2.9 pounds. An absolute bargain by any measurement. Very highly recommended.

I watched a few episodes of Handmaid's Tale Season 2 on Hulu with the Sprout 100 and the LS50s, and the sound was so good I didn't miss a center channel speaker (in part because I was sitting equidistant from the left and right speakers). Stereo imaging was broad and sharply focused in ways you'll never hear from a sound bar.

So yes, the PS Audio Sprout 100 is an overachiever, just pair it with a good set of speakers and you'll be good to go.

PS Audio knows the importance of maintaining tonal integrity and placing musicality above all else. No matter how smartly engineered, elegant, or expensive a piece of gear is…it’s fruitless if it ignores these key ingredients. These qualities are what makes something captivating and keeps you in your seat.

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.

The goal of the Sprout100 was to provide quality sound without the hassle. They’ve not only succeeded but also went above and beyond. Instead of being a stepping stone into great sound, I think the PS Audio Sprout100 could be your long-term cornerstone as you scale up. It has the power. It has the flexibility. And it definitely has the sound.
