TEAC- USA TEAC UD-507 USB DAC/Headphone Amplifier/Preamp
Completely redesigned 500 Series DAC/Preamp/Headphone amplifier with high-end 700 Series design concept in a compact A4-size package.
The UD-507 is equipped with our proprietary “TRDD 5” discrete DAC, designed with musicality as the top priority. Following in the footsteps of TEAC's acclaimed 701 series,
the new “TRDD 5” discrete DAC offers a clear soundstage and accurate imaging, providing listeners with a truly immersive musical experience.
Fully Balanced Dual Monaural Headphone Amplifier
The UD-507 is a headphone amplifier featuring the TEAC-HCLD2 high current line driver, which is characterized by its high current supply capability.
Compared to the previous model, the maximum output power has been greatly
improved by strengthening the power supply, resulting in a generous driving power of
1,200mW + 1,200mW (balanced output at 100 ohm load), which is comparable to a dedicated headphone amplifier without DAC.
The power amplifier gain can be switched between 3 positions (Low/Mid/High)
to fine-tune the output to best match the sensitivity and impedance of the headphones.
High-Quality Preamplifier with Multiple Analog/Digital Inputs
The UD-507 incorporates the TEAC-QVCS high precision analog volume attenuator
and the powerful TEAC-HCLD2 high current line buffer circuit.
With five digital inputs and two analog inputs (unbalanced and balanced),
a wide variety of devices can be connected.

What Reviewers Are Saying
Pros
Clear, spacious soundstage with precise imaging from the TRDD5 discrete DAC design.
Strong balanced headphone output, rated at 1,200mW per channel into 100 ohms, with improved power supply capability.
Exceptional connectivity and system flexibility: digital and analog inputs, Bluetooth LDAC/aptX HD, plus balanced and unbalanced outputs.

Cons
No built-in network streaming, despite its otherwise comprehensive feature set.
Premium pricing is high compared with lower-cost alternatives from WiiM and Schiit.
SOUND QUALITY PERFORMANCE 83/100
The supplied coverage highlights an immersive presentation with clear soundstage and precise imaging, alongside substantially increased headphone output versus the previous model. It provides little independent listening detail on tonal character, low-level noise, or real-world pairings with specific headphones and IEMs.
Transparency Resolution
84/100
The coverage describes a clear soundstage, precise imaging, and the ability to reveal breadth and articulation in familiar recordings. This is encouraging evidence for an open, well-separated presentation, though detailed comparisons of resolution and fine-detail retrieval are not provided.
Tonal Balance Musicality
82/100
TEAC's stated aim is a more immersive musical experience, but the supplied coverage does not characterize the UD-507 as warm, neutral, analytical, rich, or bright. There is therefore little direct information about timbre or long-term tonal balance.
Dynamics
84/100
The revised power supply and HCLD2 output buffer are presented as delivering stronger current capability, with 1,200mW per channel balanced into 100 ohms. The available coverage does not include listening observations about transient attack, punch, or performance with difficult planar loads.
Noise Floor
82/100
The supplied coverage does not report hiss, hum, background silence, or use with sensitive IEMs. It also does not provide low-volume listening observations that would establish how quiet the amplifier is in practice.
Headphone Compatibility
83/100
The UD-507 offers single-ended, 4-pin XLR, and 4.4mm headphone connections, with stated support for 16-to-600-ohm headphones and appreciable output power. Those provisions suggest broad intended use, but the review provides no specific headphone or IEM pairing results.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
82/100
The coverage notes TEAC's Quad Volume Control System and high-current line buffer circuit, indicating considered analog control and output implementation. It offers little direct commentary on chassis execution, controls, connectors, thermal behavior, or long-term durability.
Features Usability
92/100
This is a notably versatile DAC, preamp, and headphone amplifier, with USB-C and USB-B, coaxial and optical inputs, Bluetooth with LDAC and aptX HD, balanced and unbalanced analog inputs, and balanced headphone connections. The supplied coverage says it packs in substantial setup flexibility, while also noting that network streaming is absent.
Value for Money
82/100
At roughly $2,100, the coverage considers it expensive beside lower-cost alternatives from WiiM and Schiit. It also finds that the wider connectivity and digital-format support make it worth a closer look, softening rather than eliminating the price concern.
