Optoma NuForce uDAC-3 USB Digital Audio Converter - Silver

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.

yes i can hear the difference. worth the money.

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

I bought this on a whim when the price fell sharply for some reason.I was pleasantly surprised at the small size of the device and the music quality that it produced.However I only used it a handful of times and recently the USB input to the device that connects it to a laptop/PC broke off.It was definitely not through misuse and now the input port is rattling inside the device and it is rendered useless.Worst is that it has only passed the returns window by to weeks.So in the long run it has been costly device that was used a few times and it now useless.I saw another review on here which showed that this is a common problem.USB input is the only weak part of the overall design but it is a fatal flaw.Avoid buying unless you cover yourself with an extended warranty!!

This is a superb piece of equipment being small, easy to use and fantastically enjoyable to listen to. I have used it almost daily with my Mac and a lossless streaming service and paired with B&O H6 it makes me smile every time I use it. In direct comparison with other, much more expensive, headphone amp/dac combinations it also holds its head up high and easily performs at a level above it's price point.

Very high quality dac/amp, excellent sound quality, great build quality, I also own a very expensive headphone amp I've had for years and it's on the same level as that, great value, will improve the sound hugely if you have a crappy sound card, no brainer just pick it up, i'm using it every day, very sweet.

A very good little DAC serving as headphone amplifiers on the job. It is solidly built of aluminum and works flawlessly. Just plug it in and enjoy. I bought it because I experienced bass in my headphones that was so thin and tinny, especially from my PC. Using this, there is more pressure in the base and the sound is so much clearer and full. I haven't bought anything like this before, but the sound quality seems lossless, rich and gorgeous. The unit itself seems very well made, and in comparison to other devices in this genre, it's well priced. I would possibly say it is an entry to mid level device, and perfect for audiophiles with a decent pair of headphones.

Impeccable audio quality, I can actually hear each layer of audio and it's crystal clear - amazing!Got mine from massdrop on black friday - no regrets.

Je l'avais sélectionné pour le mettre entre mon NAS (Synology DS216J) et mon ampli HK pour pouvoir directement écouter des MP3 sur ma chaine ... Il ne fonctionne pas alors qu'à partir de mon PC portable il fonctionne !!! Synology s'est contenté de me dire(sans faire le moindre test) qu'il ne fait pas partie de leur liste des "compatibles" alors que le UDAC2 (qui ne se trouve plus) l'est...Donc retour chez Amazon sans problème.

Mi Fiio E10K lo supera ampliamente en lo referente a la amplificación del sonido, tiene muy poca potencia y cualquier cosa superior a 100ohms se va a quedar desaprovechado. Su enorme ventaja es que se puede usar sólo como DAC para alimentar monitores autoamplificados y su calidad de sonido es muy buena, con cierto tono cálido en la música. En el apartado de calidad de sonido sí que gana ampliamente al Fiio E10K, ya que este último sin el bass boost suena "esteril", muerto y si le pones el bass boost va pasadísimo de bajos y distorsiona.Otro defecto es que no reconoce en Windows la resolución 24/96, aunque sí reconoce los 16 y 32 bits. Es un "bug" conocido por Optoma y he probado a reproducir archivos FLAC a 24/96 y sí los reproduce pero me parece una chapuza.Pero en general es un MUY BUEN DAC, y la amplificación buenísima si no pretendes mover "monstruos".

Recommendé par un ami, je recommande vivement moi aussi, après 1 an d'utilisation. Il est connecté a 1 NUC , j'ai un retour audio sur ma central Russound du tonnerre, je profite enfin de l'audio.

Acheter pour passer de la musique depuis un Synology vers un Amplis pour une de chaine Hi-Fi.Présence d'un sifflement continue , avec ou sans connexion wifi.

il primo ho dovuto rispedirlo indietro perché pensavo fosse rotto invece anche il secondo ha mostrato problemi di connessione USB su iMac con OSX El Capitan 10.11.4. Solo dopo aver provato diverse porte ne ho trovata una funzionante, inoltre in un paio di settimane di utilizzo quasi continuo (durante tutta la giornata) ha avuto 2 momenti di malfunzionamento, anche se è bastato scollegare e ricollegare il cavo.Il problema riscontrato è una fortissima distorsione del suono, che gracchia e viene molto rallentato.Durante il normale funzionamento invece suona molto bene, l'uscita audio del PC ha guadagnato in modo sensibile, testato con casse EmpireDimensioni e peso molto contenute (il cavo RCA lo solleva in parte).PRO: buona qualità audio, manopola volume analogica, belle finiture, su iMac apprezzo la possibilità di avere un'uscita cuffie frontale.CONTRO: errori di connessione USB su OSX El Capitan, cavo RCA non incluso
