I hope they're in progress, particularly in light of the 2015 model's rather unusual results.

a Class C recommended component? ( or is it made by someone else )

Are we apologizing here or is this thingy an entry level Computer Audiophile device like the cheap ( made in USA ) Schiit stuff?

Seems like everything else PS offers ( and make in Colorado ) is way up on the top of Class A recommended lists.

If Sprout100 gets a Class-A recommendation, that would be the end of civilization as we know it :-) .........

I appreciate the new review and am wondering what a similarly budget conscious pair of bookshelf speakers be? Preferably well-rounded ones that don't necessarily require a subwoofer and would, of course, match well with the Sprout100. Double bonus points if they don't have a rear firing port as space is very much at a premium in my room.

... of the Sprout and Elac Debut 2.0 speakers:

Not bad for $249 speakers!

You state that the new Sabre chip reads signals up to 384 kHz, but the specifications above say the unit will read only up to 192 kHz. What is the source of this discrepancy?

Hope they got rid of this BS massive fixed bass boost that JA measured with the earlier one.

HR talks about the 'bass boost' in the review and how to get rid of it :-) .........

There's "talk" of a button on the back, but there's nothing to see on the web with some good pics of the rear of the old one, and in pics of this one above.

I could not find any info on disabling the original Sprout's bass boost - no switches and nothing in the user's manual.

Regarding the Sprout 100 and it factory default bass boost, Herb wrote, "bass boost is automatically engaged at turn-on... said user must push in the Volume/On/Off knob and hold it there a few seconds..." to turn it off. Also, from the user's manual, "To enable or disable the bass boost simply long press the volume knob to toggle the feature on or off." It does not appear to have any switches other than the Volume/On/Off knob to control the bass boost.

I am a some-what seasoned audiophile and own the Sprout 100. I love it! I'm using it in a small living room with B&W CM5S2s and a MacBook Air. This is the same room that used to have Magnepan 1.5s with ARC LS8mkII / 100.2, linn CD player and a Linn LP12. I have to say that I really enjoy the simplicity of the sprout system and play it a lot more than I did the ARC system. Although I have another room now for my "serious" system (no longer the magnepans - were replaced with KEF) we spend a lot more time in the living room with the sprout. I find that it has plenty of detail, imaging and all the other "audiophile" qualities that seem to make listening to music more like a live experience. This system really does a great job of making music!!!

May be HR could review the new Sprout100 with Mini-Maggie desk top speakers :-) ............

The original Sprout was listed in Class C of Stereophile's Recommended Components, and we were proud to have it there. As you can imagine, it's especially challenging to build a moderately-priced component that compares to our Stellar or BHK series components, and I think the PS team has done a terrific job of meeting the challenge---there's a lot of high-quality componentry in that little enclosure!

The boost in Sprout100 is user-defeatable by way of the right-hand knob/on-off/volume control. In daily usage with speakers of moderate size, the boost in the original unit was rarely noticeable or intrusive.

Finally: I will very mildly take issue with Herb's final comment. We've sold thousands of Sprouts and Sprout100s to longtime PS customers who own "Big Boy" systems, who use their Sprouts in offices, vacation homes, simple systems, and have given them as graduation and holiday gifts to their offspring, relatives, and friends. We've also had a rave review from a website devoted to simple tech for the 50+ set. Just a matter of perspective, I guess!

Happy Halloween!
