TEAC Audio UD‑701N

The TEAC Audio UD-701N combines flagship-level USB DAC conversion, high-resolution streaming and analog preamp functions to serve as a modern hub for elite systems.

Product Description

The TEAC Audio UD-701N is a reference-grade USB DAC/network player/preamp that integrates true high-resolution digital playback, analog input/output flexibility, and a robust headphone amplifier — making it ideal for audiophiles and system integrators. It uses TEAC’s newly developed “ΔΣ discrete DAC” architecture in a dual-mono, fully balanced circuit layout for extremely refined sound reproduction. 

As a network player, the UD-701N supports PCM up to 384 kHz/32-bit and DSD up to 22.5 MHz, plus full MQA decoding, Bluetooth with high-quality codecs (LDAC, aptX HD), and streaming services like TIDAL/Qobuz. 

 It also provides analog line-level inputs (balanced XLR and unbalanced RCA) making it function as a preamp for analog sources. 

On the output side, the UD-701N features balanced XLR and RCA outputs with variable or fixed volume settings, and a dedicated headphone amplifier capable of 700 mW per channel into 32 Ω (balanced) — making it very capable for high-end headphone listening. 

Overall build, advanced feature set, and audio performance position the UD-701N as a central component in high-fidelity systems.
