DSD 5.6MHz / PCM 384kHz capable Dual Monaural D/A Converter
TEAC’s new UD-501 is the star of the 501 series. The UD-501 supports Direct Stream Digital (DSD) playback at either 2.8 MHz or 5.6MHz (DXD) rates. PCM audio is supported up to 384kHz/32-bit resolution. It connects to your computer over USB using ASIO 2.1 or DoP.
The output section of the UD-501 features two BurrBrown 32-bit DACs per channel and JRC MUSES op amps, also with a dual monaural design. Both balanced XLR and unbalanced RCA outputs are available to connect to your power amplifier. A toroidal-core power supply ensures top performance and clean transient playback, for quality that outperforms components five times its price.
AWARDS
Audiostream awarded the UD-501 their Greatest Bits award in a rave review, in which the reviewer "Debated delaying this review so I could [...] find something more, ah hem, critical to talk about." "The UD-501 invites you into each musical performance making it downright difficult to leave."
In Japan, the UD-501 has been awarded the VGP (Visual Grand Prix) Gold Award, one of the most famous in the Japanese AV equipment market. It was also awarded the AEx (Audio Excellence Award) and AEx Extra Award for pure audio equipments.

Features
at a glance
Both 2.8MHz and 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)
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 Noise 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.
Pure Audio Circuits With Classic Audio Pedigree
Dual Monaural Circuits to Eliminate Signal Interference and Maximize Performance.
Every single part of the digital and analog sections are designed in dual monaural design to eliminate interfering noise to other channels. This maximizes the potential of the the DAC and the operational amplifiers, and achieves a purer audio processing signal.
32bit-compatible BurrBrown PCM1795 on Each Channel The celebrated BurrBrown PCM1795 D/A converter is used on each channel, which supports 32bit audio with a 123dB S/N Ratio. Dual MUSES8920 Operational Amplifier on Each Channel Two MUSES8920 operational amplifiers are used on each channel. The MUSES8920 was developed for hi-fi components to deliver clear, 3-dimensional sound. Individual Toroidal-core Power Transformer on Each Channel – Maintaining Total Dual Monaural Design The two toroidal-core power transformers offer a stable current supply withenergy-effcient operation. Using a pair of power transformers, one each for the left and right channel, ensures that current is delivered exclusively to each channel.
RCA Output with Parallel Buffer for Better Drivability Two operational amplifiers are connected in parallel with the line out circuit section to improve of line-out signal drive. This helps achieve a more linear analog output signal than any other known method.
High-Standard Hardware Designs for Any Listening Environment
▲To TopA full-metal body, small footprint that can be placed on a desktop
The front, side, and top panels are each constructed of aluminum and attached to a robust steel chassis. These heavy parts eliminate vibrations, allowing internal circuits to 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.
A Large Number of Inputs & Outputs for Full-Scale Hi-Fi System IntegrationThe 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 to either RCA or XLR. The XLR output connectors have switchable polarity, either pin 2 HOT or pin 3 HOT, to accomodate vintage amplifiers. A standard detachable IEC cable with 3-polar socket allows user to upgrade to high-grade AC cables.
