Product Description

NOTE : Note that the USB cable may remain connected on the product side, which will avoid worrying about the above precautions.


The uDAC3 Digital to Analogue Converter (DAC) and combined headphone amplifier significantly upgrades any computer's sound output. It simply connects to the computers USB port and extracts every last nuance and detail from your digital music collection.

Small enough to fit in your pocket, but packing the serious earphone power required to produce the extra bass and volume in the noisiest of environments, the uDAC3 helps you to enjoy perfect sound from your laptop wherever you are. The uDAC3 uses USB for the audio connection, bypassing your laptop's soundcard and earphone output. It then processes your digital music directly - giving you much better sound than is possible from your laptops earphone output. The uDAC3 is perfect for use at home as well as when you're out and about. Unusually for an ultra-portable DAC, it has both analogue and digital output connections - in addition to the earphone amplifier - so you can connect it to your amplifier and speakers at home or in the studio.

The uDAC3 is not just for music lovers; if you're a gamer you will experience a more accurate and realistic sound track, and you'll hear subtle audio cues that others won't, therefore increasing your performance and enjoyment. Musicians, producers and DJ's can use the uDAC3 as an ultra-portable monitoring solution enabling them to work anywhere with ultimate precision. If you use Skype, YouTube, watch movies or use online music services (like Spotify or Pandora) the uDAC3 provides you with the perfect audio accompaniment.

For sound quality it's brilliant, I plugged my Sennheiser Momentum's in and now I have a new appreciation for how good they are. This little box of wonders is fantastic, it's small and easily tucks away. But...... i've had it for just over 4 weeks now and i plugged the usb micro cable into the back of it and the port popped through into the box and is now rattling around inside making it unusable and broken. The build quality needs to be stepped up and I'll be asking for a refund and maybe trying it again because the sound that it made was fantastic

Really pleased with this DAC. I have had another NuForce amp for a couple of years to output music from my TV through large speakers and it has been brilliant. So when I saw these on a Lightning Deal I went for one (and discovered they had previously been even cheaper, albeit very briefly).
I have to say I am very impressed with the clarity and depth of sound. Music through my P7 B&W headphones from a MacBook Pro, switching between the normal 3.5mm socket and the DAC is immediately noticeable, even to my rubbish hearing.
The unit is tiny but solid and well made. I haven't yet tried the Co-ax or analogue RCA's through my hifi but I have no doubt they will be equally impressive and immersive.
Sadly, as advertised, it does not pick up a signal from my Android device (unlike other DAC's which can!) but for getting SACD quality sound from a PC/Mac I can highly recommend it.

This is not a paid for review btw.

Colour: Black Vine Customer Review of Free Product ( What's this? )
This Optoma NuForce uDAC-3 is the business if you want to enhance your listening experience with headphones
for a computer with digital music, games, or by linking it up with your speaker to a hi fi system.

Firstly though, the instructions with the product are sparse. Not that its difficult to work out, by utilising your settings,
(My computer is a Mac,) and your a ready to go. I have a wide taste in music from rock to classical, and there is no doubt
that there is a greater clarity with the sound and a significant boost to the volume.

It is the same process if you wish to build up your sound experience with games. For me this was a standout feature. Using headphones
the result was a definite level above the normal experience.

The other option is to link it, to your speakers, on your hi-fi system. Again, this was achieved successfully without fuss.

There is no doubt it is a cracking little, (unobtrusive,) unit which generates a great sound.

If you are considering buying a uDAC Digital Audio Converter then this could be for you. Recommended.

Colour: Black Vine Customer Review of Free Product ( What's this? )
I already own a FiiO E10K Headphone Amplifier and DAC and have always been really happy with the sound quality it delivers, so I wasn't sure what to expect from the slightly more expensive NuForce uDAC-3. More cynical music lovers might wonder how much difference there can be between such digital devices, but I tried to test the uDAC-3 with a completely open mind using my much loved Creative Aurvana Live! Headphones and I'm really glad I did - it's fantastic! After using it for just a few days, I decided I actually preferred it to my FiiO and now I use it all the time at home. The FiiO (which is still a really good DAC) now gets used at work instead!

The device itself is very simple and clean. The black outer casing is actually metal rather than plastic and feels solid to the touch. It's still compact enough to easily slip in your pocket if you want to use it on the move or carry it with your laptop. There's a solid rotary volume knob on the front, next to a subtle power LED and the 3.5mm headphone output socket. On the back you get a micro USB socket for connecting to the computer, a couple of RCA line output sockets and a digital coaxial output socket should you need them. Installation is an absolute doddle on Windows 8.1 and Windows 10 - just plug in and go; Windows has all the necessary drivers built-in. I see some other reviewers were not happy with the supplied instructions, but really there's not much to know - just plug it in to your PC and connect some headphones!

Colour: Black Vine Customer Review of Free Product ( What's this? )
I received this product and was immediately impressed with its apparent build quality. A solid feel, edges meeting just like edges should and it feels really nice. I plugged it into my laptop USB port and instantly it took control and I gave a lovely quality sound so much more superior and better by far than the speakers could manage. Unplugging immediately returned control to the system.
Unfortunately, that was it, I couldn't get it to work properly on any one of three desktops, The sound configuration was lost and had to be reset, but returning to the laptop, it worked perfectly.

Ha! I thought, time to check out the customer services. I emailed and in good response time, received the normal advice about drivers and switching off and on again, trying to re-boot with it out and plugging in, rebooting with it in etc.. Bless 'em they weren't to know all this and more had been tried, so after a couple of days emailing back and forth, they wanted the unit back for examination, at no time did I mention I was doing a review on the product so I would get their normal response to my queries.
A courier was sent to pick it up followed by an email to confirm it was a faulty unit. It is now on its way back to me so I will add to this review next week (week commencing Monday 13th Sept 2015) and hopefully it will work as expected in all my units. It does give beautifully clear sound through my headphones on the laptop and if it does work as expected on the other equipment its well worth its purchase price and of course I can vouch for the support given.
Unfortunately there was a delay in sending the item and I would not be at home when it was due to arrive, so I asked that it be delayed until my return, this was acceptable and I will contact them on my return.
