DSD 5.6MHz and PCM 32bit/384kHz-Capable
The star of TEAC’s 501 series, the UD-501 Dual Mono DAC supports DSD 2.8/5.6MHz file native playback by ASIO 2.1 or DoP methods or up to 32bit/384kHz PCM. TEAC also packed this incredible unit with two 32-bit BurrBrown DACs per channel and JRC MUSES op amps, dual monaural design, fully balanced XLR as well as unbalanced RCA outputs and a toroidal-core power supply. The UD-501 outperforms DACs far outside its price point. Amazing sound, unbeatable feature list. We guarantee you have never heard any DAC under a grand sound as fabulous as this one!
“The TEAC UD-501 is an extremely impressive DAC. It plays every audio file you could conceivably think of, and does so while cocking a rather large snook at companies that insist DSD replay is only possible at great expense. An integrated streamer aside, I can’t think why anyone would want anything more than this. Strongly recommended!”

- DSD 2.8/5.6MHz Native File Playback by ASIO 2.1 or DoP
- Both 2.8/5.6MHz DSD files are processed in native mode to properly convert DSD into an analog signal, and skipping PCM conversion in between. ASIO2.1 and DoP (DSD over PCM) playback are also supported. (Mac supports DoP only, with standard driver)
Asynchronous Transfer Mode
By ignoring clock signal from a PC, transfer timing is controlled by more accurately, nearly eliminating clock-noise and allowing digital data to travel unaffected.
Variety of Settings to Match Your Preference
Three types of digital filters are provided for PCM playback, while 4 types of cut-off filters are provided for DSD playback. Also, shutting down unnecessary circuits – USB circuit when S/PDIF inout is selected, or Line Out circuit when Headphones are connected – for purer audio processing.
Reducing Jitter by 192kHz Up-Converting
With a PCM file sampling at a frequency less than 192kHz, users are able to convert up to 192kHz in order to reduce jitter noise, or keep the original sampling rate to enjoy the original sound.
Dual Mono Circuits Eliminate Signal Interference
Every single part, the digital, analog sections, the DAC and the operational amplifiers are designed in dual monaural design to eliminate interfering noise to other channels. This maximizes their potential, and achieves a purer audio processing signal.
32-bit-Compatible BurrBrown PCM1795 & MUSES8920 Operational Amp on Each Channel
Celebrated BurrBrown PCM1795 is employed on each channel. With the PCM1795 alone, it supports 32bit processingis supported with 123dB S/N Ratio. Additionally, two MUSES8920 operational amplifiers are employed on each channel. The MUSES8920 was developed for hi-fi components to delivers clear 3-dimensional sound. The two toroidal-core power transformers are highly energy effcient and offer a stable current supply. Employing them on both the left and right channel ensures that current is delivered to each channel, exclusively.
RCA Output with Parallel Buffer
Two operational amplifiers are parallely connected with the lineout circuit section to improve drivability of lineout signal. This helps achieve more of a linear analog output signal, than any other known method.
Rugged Metal Body, Small Footprint
Not only the front panel, but both the side and top panels are constructed of aluminum and attached to a robust steel chassis. These heavy parts eliminate vibrations, and allow all internal circuits to always perform under stable conditions. An A4-size body allows the UD-501 to fit any small space. The Reference 501 series defines a new standard to fit all modern interior, with great space-saving design and a timeless presence.
Numerous Inputs & Outputs
The UD-501 provides two optical and coaxial digital inputs, one pair of XLR and one pair of RCA analog audio outputs. The RCA lineout jacks have an exclusive clearance zone, so a high grade pin cable with a large shell is able to be connected. The output terminal is selectable:-RCA or XLR; the XLR connectors have switchable polarity, 2=HOT or 3=HOT. A detachable AC cable with 3-polar socket allows user to upgrade to a high-grade AC cables.
