      "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..."

    • Paul Cash, Hi-Fi Trends

      "The Sprout 100 is a musical integrated amp that gives you so much for your money. The Headphone Amp/DAC alone is worth what they charge for this thing, but then when you factor in the power amp that drives speakers down to 4 ohms, the Bluetooth streaming, phono pre-amp, etc. you can see this product is an excellent value. This integrated would be a perfect product for young guys putting together their first hi-fi setup, or someone who wants a quality amp and doesn't have a lot of room to spare..."

      "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..."

    • Gary Allen Barker, Headphone Guru

      "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..."

    • John Richardson, Part Time Audiophile

      "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..."

    • Steven Stone, Home Theater Review

      "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..."

      "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. This isn't about specs and numbers, this purely..."

      "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..."

      "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..."

      "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..."

      "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..."

      "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..."
