Our take on the TEAC UD-H01 by Crutchfield's Dave Bar
Desktop digital dynamo
TEAC's UD-H01 digital-to-analog converter proves that full-sized sound doesn't always require a full-sized component. Just plug your computer into this compact desktop DAC's USB input to enjoy big-time sound qualiy with the music on your PC. The TEAC works wonders with uncompressed high-res and lossless music files. And even Internet streaming audio sources sound more fleshed out — not just listenable but actually enjoyable. The UD-H01 performs much better than even high-quality sound cards, which are handicapped by having to operate in the noisy environment inside your computer. Plus, its classy, slimline form will look great in your home or office.
Ready for high-res music
Versatile digital music handling comes courtesy of dual built-in Burr-Brown DACs that support high-resolution sampling rates and bit depths up to 192kHz/32-bits. The UD-H01's asynchronous USB input allows the DAC to control the timing clock signal instead of your computer, reducing jitter to the lowest levels possible for smoother, more detailed sound. The TEAC website has all the free USB driver downloads you'll need for computer playback available online. The UD-H01 also takes advantage of a beefy toroidal transformer-based power supply and dual-mono circuit design throughout for powerful sound, optimum channel separation, and clear stereo imaging.
The ins and outs
The TEAC UD-H01 sports multiple inputs and outputs to handle your audio system's needs.
This DAC features three inputs: the aforementioned USB, plus two digital inputs (1 coax, 1 optical) for connecting a CD/DVD player, game console, or other audio device with a digital output. You also get both unbalanced RCA and balanced XLR audio output connectors to hook up a pair of powered speakers or an external amplifier. Or, keep your listening immersive and private by plugging in to the headphone output on the front panel.
The DAC is good quality that seems like a sturdy quality product. I'd recommend this DAC to anyone looking to improve sound qualiy.

TEAC UD-H01 Reviews
Average Customer Review(s):
Thanks for submitting your review
USB Audio DAC: The TEAC UD-H01 features coaxial and optical S/P DIF digital audio inputs, as well as a USB port to allow use as a high-quality D/A converter. These digital inputs connect to a premium-quality Burr Brown PCM1795 dual DAC with up to 192kHz/32-bit audio resolution for the highest-quality sources. The device can receive data asynchronously meaning the timing signal is included reducing jitter to the absolute lowest level. Input sources can even be up-converted to higher sampling rates for smoother audio quality. Output terminals include gold-plated RCA connectors, line-level output and XLR balanced output terminals for connection to a full-fledged high-end operation amplifier.
Dual Monaural Configuration with Independent Left/Right DACs: The TEAC UD-H01 incorporates two 32-bit/192kHz Burr Brown D/A converters (PCM1795); one for each channel. The dual-monaural configuration eliminates interference between the channels for maximum performance from the D/A converters. A shunt-regulator circuit supplies the current to the D/A converters in order to eliminate ground noise generated by fluctuations in the supply voltage
192kHz Up-Conversion: All digital input signals are converted to 192kHz via non-integral up-sampling, dramatically reducing jitter and allowing consistent D/A conversion based on the high-precision internal clock. ASRC (Asynchronous Sampling Rate Converter) is used to produce a natural, 192kHz high-sampling rate digital audio signal.
Supported Formats: The TEAC UD-H01 is the perfect DAC for playback of high-resolution computer formats like FLAC, WAV, and Apple Lossless. Its three digital inputs (optical/coaxial/USB) support sampling rates of 32, 44.1, 48, 88.2, 96, 176.4, and 19kHz. 16- and 24-bit rates are supported. There are six front-panel LEDs (44.1/48/88.2/96/176.4/192) to indicate which sampling frequency is being input.
USB Type-B Port for Computer Audio Streaming: The TEAC UD-H01 features a USB (type-B) port for connecting your Windows PC or Mac computer. The UD-H01 digitally transfers audio source material stored on your computer to your connected amplifier at up to 24-bit/192kHz. The UD-H01 also supports USB asynchronous mode, which uses its precise internal clock to control timing and eliminate jitter issues. This allows optimal playback of high-resolution digital audio files from playlists/libraries in your iTunes, Windows Media Player, or similar playback programs on your computer. This unit does not offer control over your computer's music files.
Note: Before using the UD-H01 with your computer, you will need to download and install the dedicate TEAC driver on your Windows PC or MAC. Supported operating systems included Windows (XP*/Vista/7/8) and Mac OS X (Snow Leopard/Lion/Mountain Lion). *Windows XP Professional x64 Edition is not supported.
Optical & Coaxial Digital Inputs: The TEAC UD-H01 is fitted with optical (toslink) and coaxial (RCA) digital inputs for connection of other digital audio sources like your CD, DVD, or Blu-ray player. These digital inputs will accept two channel linear PCM (not Dolby Digital/DTS).
Independent Balanced & Unbalanced Outputs: For output to powered speakers or an amplifier, a Muse 8920 dual-operation line amplifier terminates to gold-plated stereo RCA and balanced XLR outputs. The output circuit is completely independent in the left and right sides for optimum channel separation and clear stereo imaging.
Stereo Headphone Amp: The same high-quality operational amplifier used for line output is used for headphone amplifier output. A dedicated high-quality aluminum knob controls the headphone volume. This allows users to enjoy a high-sampling-rated digital audio in spaces with neighbors close by, or other situations where speaker playback might disturb others. The unit is fitted with a front-panel 1/4" headphone jack.
High-Performance Power Supply: The UD-H01 uses a high-capacity toroidal-core power supply transformer capable of providing a stable current with high efficiency. This minimizes flux leakage and eliminates noise generated by electromagnetic induction.

4 questions already asked
No, the unit is not compatible with Dolby or DTS. Its primarily designed for music playback and only has a 2 channel output. You should still be able to use it with a Blu-Ray player, Apple TV, etc. but you'll need to set the audio output of your source device to stereo rather than surround. [ Eric Aug 23, 2014 ]
It works real well and the headphones are closer to where I sit that before. [ Harry Aug 22, 2014 ]
No, it converts a digital stream into 2 channel audio output. [ ROBERT Aug 22, 2014 ]
No, the TEAC unit is 2 channel only. [ RICHARD A Aug 22, 2014 ]
I'm gonna say NO. The rep who sold me mine said not to play those Special High Quality CD's through the device. You best bet is to read the manual from the TEAC site or call a crutchfield representative. The unit does not encode or decode Dolby Noise Reduction (a dinosaur of old tech aids). [ BRIAN Aug 22, 2014 ]
It doesn't I believe. You have to have the device set to pcm or whatever . [ LUCIAN H Aug 22, 2014 ]
Yes, from a blu-ray player it will work - not sure about a streaming device. [ Jose Aug 22, 2014 ]
Hello Rob, If you meant streaming music I believe you can. I am not sure what kind of device you have in mind, but for example I have Peachtree Bluetooth DAC which can output uncompressed signal to the UD-H01 streamed from an iPhone. In this application you are bypassing the internal DAC and are using only the Bluetooth capabilities of the device. Regards, Mario [ Mario Dec 22, 2014 ]
Thanks to Eric and all others who answered my question. Rob [ Rob Dec 22, 2014 ]
Yes, you can absolutely connect this to an Apple TV with an optical cable. I currently have an Audioengine D1 connected to my Apple TV, and it sounds great using Airplay. This is probably an even better choice for that application due to the built in power supply and overall quality. Just keep in mind that this (and any) audio DAC is designed for 2 channel music playback, and does not support or decode any surround sound formats. [ Eric Dec 21, 2014 ]
I'm not sure about an Apple TV but you can stream wireless to an Airport Express and use the optical out into the H01 to accomplish that. I've never tried it with the Apple TV but I know it works with the airport. If your airport/apple tv aren't close to the H01 you could get a long optical cable to connect them together. I've seen 100+ feet cables work at 16/44.1 [ Nikolas Dec 21, 2014 ]
Yes, that will work, but remember that the Teac will only output 2 channel stereo. I have a cable box optical output into my Teac, solid improvement over using the TV's audio outputs into my 2ch preamp. [ ROBERT Dec 21, 2014 ]
I have Apple TV hooked into the game input and I'm able to stream from my iphone and ipad. And of course if you have a MAC, you can mirror directly to Apple TV. [ ANTHONY J Dec 21, 2014 ]
1 answer I'm interested in this mainly as a way of outputting my FLACs (I've ripped myself, with the highest quality) to my mid-end system (Paradigm 100 Studio loudspeakers, Anthem 225 amp) through the XLR output. I would also see if it'd better than current CD's DAC (which also is BurrBrown but not 32) Two questions: 1) Is this product affected by the Intel Haswell v4 USB issues, present MacAir and Wintel laptops from 2013 and on? 2) Will it work on Linux (kernel 3.11 and above), e.g. a Debian-based distro? Thanks in advance [ XLR guy Nov 04, 2014 ]
I forwarded your question to an Advisor and they responded with the following: 1.) We do not have any details on this, you may want to call TEAC at 1-800-447-8322 to see if they have further information. 2.) It is an unsupported operating system by TEAC. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Nov 10, 2014 ] Staff
Unfortunately not (I wish it did though), the volume knob only controls the level of the built in headphone amp. When using speakers, you'll need to adjust the volume on your amplifier or the source (iTunes etc.). The DAC sounds great, I recommend it. [ Eric Jun 30, 2014 ]
No, it does not. The volume control is for the headphone (analog) output only. I'm running my UD-H01 through balanced outputs to the preamp section of my Wyred4Sound integrated amplifier. Selecting a digital source and moving the volume knob does nothing whatsoever to the amplifier output. [ David Jun 30, 2014 ]
The answer to your question is no. The volume knob only adjusts the phones level. You would need to adjust the volume level of your preamp or amp for volume control for usb or digital sources. Jim [ JAMES R Jun 29, 2014 ]
No, only works for headphone volume/amplification. Signal continues to preamp/amp without effect. [ Richard Jun 29, 2014 ]
The volume control is only for the head phone output. This unit is not a preamplifier, the balanced and unbalanced outputs on the rear are fixed. [ RICHARD A Jun 29, 2014 ]
No.....Stereo Headphone Amp: The same high-quality operational amplifier used for line output is used for headphone amplifier output. A dedicated high-quality aluminum knob controls the headphone volume. This allows users to enjoy a high-sampling-rated digital audio in spaces with neighbors close by, or other situations where speaker playback might disturb others. The unit is fitted with a front-panel 1/4" headphone jack. [ RONALD E Jun 29, 2014 ]
The volume knob on the Teac UD-H01 only works with the headphone out jack (TRS) - Otherwise it is totally passive. I use mine to feed a Schiit Mjolnir via balanced output (XLR)... I hope this helps... [ Jemal Jun 29, 2014 ]
While the owners manual does not answer your question, there is one clue in a description of the product. "The UD-H01 is supplied with both balanced and unbalanced audio output connectors and a headphone connector complete with separate volume control." Disregarding the "Ballanced" and "Unballanced" comment the statement "a headphone connector complete with a SEPARATE volime control." is key to my believing it does not alter the volume signal to an amplifier, which has a volume control of it's own. I have not yet set my system up in this configuration yet and thus can not be 100% sure. It would make sense not to not be able to alter the input volume to an amplifier. [ BRIAN Jun 29, 2014 ]
No, the volume knob only controls output to the headphone jack, (which is quite good,btw, if you wanted to get into quality headphones)not to the analog outputs. However, both Schiit and Emotiva make low cost,quality analog volume controls which will work well with the HDU-01 when driving a separate amplifier. [ ROBERT Jun 29, 2014 ]
No, the volume knob only adjusts the headphone jack output. [ PAUL Jun 29, 2014 ]
No, the volume control is for headphone volume only. [ Paul Jun 29, 2014 ]
The volume knob on the front of the unit is only for headphones level. This knob only adjusts for volume level output when using headphones. I hope this helps - Good Luck. -Jose [ Jose Jun 29, 2014 ]
Its for the headphones. You adjust the overall volume from your PC or Mac. This thing sounds great BTW. -Don [ DONALD Jun 29, 2014 ]
The volume knob is only for the headphone amplifier. It does not adjust the volume for any of the rear outputs, only the front headphone jack. [ Jeffrey Jun 28, 2014 ]
Thanks, John. I appreciate the response. I have 2 monoblock amps and was trying to find a great DAC to function as the preamplifier! Looks like that's not possible here. I am always told -> turn up the volume on your computer to full when sending a digital signal to your DAC. So, I'm not sure how a lower volume would sound. [ Alex Jun 28, 2014 ]
I own this TEAC UD-HO1 (Black), and what you refer to somewhat generically in your question as "the volume knob" is more specifically labeled on this USB/ DAC unit as being the knob to adjust only the "Phones Level". So, the purpose of this knob is limited to adjusting the volume of the headphones you may choose to plug into it... and that is the only function of this knob. It will not adjust the volume of any source component (CD transport, digital music player, etc.) being played through your stereo speakers, which are separately power by "an amplifier" (either stand-alone or integrated) as you indicated in your question. The volume knob on your source component, or integrated amplifier, or receiver, (depending on how you have your system wired) would be responsible for adjusting that general system volume. This is a fabulous DAC. It actually has two (2) DAC's built-in, which operate at a very impressive and rarely-seen 32 bit level (not 24 bit). Try finding those specs in another DAC priced under a thousand bucks... much less priced under three hundred as this one is. It also tells you the sampling rate being read with an LED light. The only criticism I have of this unit is that the headphone amp is not very powerful. It will only drive my low-impeadence (easy-to-drive) SHURE 1440 headphones to a "moderately loud" level at its "maximum" before it tops-out. So if you are looking for the best DAC on the market at anywhere near this price... this is it. If you are looking for a very powerful headphone amp... this is only a moderately powerful headphone amp. The physical build-quality is top-rate... finely machined aluminum and beautiful polished piano-finish top. I am pleased with it overall. [ JOHN LAWTON Jun 28, 2014 ]
