The Emotiva DC-1 Stealth DAC is frankly, an incredible value. The only other products I can think of that offers such a complete and capable skill set for such a low cost are the Koss KSC75, SennGrado, Chord Mojo, and Cavalli Liquid Carbon. Here's why:

Sound: In a word: neutral. I realize that this is a loaded term when it comes to our hobby, but here's why I chose it. The DC doesn't emphasize any parts of the spectrum to me. The low end is present and controlled, the midrange is clear and balanced, and the treble is detailed and extended. In my music-ings with this DAC, I never felt like there was any information missing. It's all there, and it's all in proportion.
Bass: The low end on this guy is pleasantly clean and full. In my experience, you often are stuck with a choice. Full low end with rolled off treble or detail for days with just enough bass to know it's there. In this case, Emotiva gives us a product that yields both. I used the DC to feed the Carbon when I had it, but with my SE headphones, I often alternated between the Carbon and the headphone-out of the Emo. With easier to drive cans like my Grados and 1+2, the bass was more extended on the Carbon, but not by much. If I wasn't A/Bing them, I wouldn't have noticed. There was a more appreciable difference between DC and Carbon for my Alpha Primes, but that shouldn't surprise anyone as the Primes love the power that balanced connections can yield.
In comparison to the Mojo, I could not hear a difference between the Emo and the DC through their respective headphone-outs. So take that for what it's worth.
Mids: Clean. To put it briefly, the midrange on the DC is just clear. It's neither forward, like the Bladelius or Starting Point DACs I used to have and it's certainly not recessed. In comparison to the Mojo with lower impedance cans, I could not really detect any differences in the midrange. Now when I used the Primes, the Mojo edged out the Emo in the midrange with regards to presence and weight, but not by a lot. Once again, if I wasn't A/Bing them, I wouldn't have noticed.
Treble: Extended, yet non-fatiguing. It seems like FOTM products nowadays are all about hyper-detail retrieval and treble energy. To my ears, that's not necessarily what live music sounds like. When I go hear a band, either in studio or at a live venue, I can't hear a cockroach break wind from behind the stage, and neither do I want to! The DC gives me just the right amount of treble presence. It's extended, clear, and very realistic. No digital glare nor tube-esque syrup. The neutrality of the DC pairs wonderfully with my Crimson, adding just enough sparkle to make the Grados sing without making me wince.
In comparison to the Mojo, the most noticeable difference between the two products was here. The Mojo did not quite reveal the same amount of upper level stuff (think cymbal nuances, finger squeaks, etc.) as the DC. Now, in most cases, the Mojo does just fine, having just the slightest smoothing of that upper end is going to make most rigs way easier to listen to, especially for long sessions. However, since I was able to compare the two, I'd give the nod to the Emo in this instance if you're considering either for mostly desktop duties.
Soundstage/Imaging/Separation: Great, not brilliant. Once again, the DC excels in 'rightness.' The soundstage and imaging capabilities are very good. Now I'm sure if I ever hear a $3k+ DAC, I'll feel differently, but for now I'm plenty satisfied. When I'm running the Emo with my Crimson, the soundstage is beautifully and accurately represented. That's all I have to say about that!
Aesthetics/Build Quality/Accessories: This is one place where the DC beats a lot of it's competition. The build quality is simply fantastic. It looks and feels like the DAC that Batman would use. Heavy duty construction, tight input/output jacks, and gratifying knobs that don't feel like they belong on a kids Fisher Price radio. I've learned that as you ascend the head-fi ladder, sound quality improvement certainly comes in smaller increments, but build quality really follows the price curve. The Emo's heft and sturdy construction (not to mention it comes with an equally well-done remote!) feels right at home with my Cavalli amp that retails for 6x as much!
I would like to say a quick piece about the headphone amp in this little guy: it's superb. Very balanced, clean, and offers quite a bit of high current power (something like 1.2W into 32 ohms I think...). Many times, the headphone circuit in a DAC is merely an after-thought courtesy. I'm happy to report that if you're a head-fier who'd like a neutrally-tuned, all in one design that really wouldn't require upgrading for a while, this is a product you need to look at. When using the Grados through the DC, I noticed very little improvement when I plugged them into the SE out of the Carbon or Mojo. Now it's not going to power an HE-6, and for the most part, a fully dedicated amp is going to offer more sonic improvement for cans like Audezes, Senns, and Hifimans, but the DC-1 really can hang with lots of headphones of mid to low impedance and power requirements.
Qualms: No real qualms, but there are a few things that the potential buyer may want to know. First, the volume is stepped in .25 db steps. That means I can really dial in my sound, but if you're using the remote or knob, things can take a few seconds to get moving. Second, the included headphone outs are 1/8" not 1/4". Now I've come to learn that that was by necessity as there's simply not enough room in the chassis to fit larger plugs, but the smaller jacks do take away from the otherwise premium feel that this DAC delivers. And finally, the power-off sequence when using the knob takes forever. I've got to hold my finger on the knob for several seconds before it goes to standby mode. Not a real issue, but annoying nonetheless.
JD's DAC Ranking list: I'm only including this since a lot of initial research was done by typing 'Emotiva DC-1 vs...' This list in based on overall value - not purely SQ.
EDITED since I've owned a few more DACs since this review: Teac UD-503 > Gumby > Emotiva DC-1 > Chord Mojo > Resonessence Concero HP > ALO Pan Am > Audio-gd NFB 11.32/15.32 > Schiit Bifrost Multibit > Centrance DACport LX > ODAC > Cambridge DACMagic 100
Final Thoughts: While Emotiva has been around for a while, we don't often see their products being touted as often as other American companies like Grado, Woo, and Schiit. I'd like to report, that if Emotiva's other products are built with the same quality standards as the half-rack DC-1, then they need to quickly move to the front of your mind when it comes to shopping for hi-fi gear. From the plethora of input options and neutral sonic signature to the very capable head-amp section, the fully balanced DC-1 represents one of the best values in head-fi. Period.
i´m looking for an amplifier for my oppo.
i have another product from jadedesign(the group of emotiva)that is the sherbourn sr-120
incredible q/p relationship
