TEAC UD-701N Reference USB DAC & Network Player

The TEAC UD-701N Reference USB DAC & Network Player is the centerpiece of TEAC's flagship Reference 700 Series, combining a high-resolution network streamer, proprietary discrete DAC, premium analog preamplifier, and balanced headphone amplifier into one beautifully engineered component. Designed for discerning music lovers, it delivers exceptional musical accuracy whether you're streaming from your favorite music service, playing high-resolution files, or connecting traditional digital and analog sources. Built around TEAC's proprietary technologies, the UD-701N is engineered to become the heart of a truly reference-quality Hi-Fi system. Why It Stands Out Proprietary Discrete DAC Technology Instead of relying on an off-the-shelf DAC chip, the UD-701N features TEAC's original ΔΣ Discrete DAC, designed entirely in-house using carefully selected discrete components. This unique architecture delivers exceptional transparency, natural tonal balance, and remarkable musical detail while supporting PCM up to 384kHz/32-bit and native DSD512 playback. Stream Your Entire Music Library Whether your music is stored on a NAS drive, computer, USB storage device, or your favorite streaming service, the UD-701N makes it instantly accessible. With support for Roon Ready, Spotify Connect, TIDAL Connect, Qobuz Connect, DLNA, OpenHome, AirPlay 2, and TuneIn Internet Radio, it becomes the central hub for virtually every digital music source. Precision Analog Volume Control TEAC's Quad Volume Control System (QVCS) independently controls the left, right, positive, and negative channels through a precision analog attenuator. This innovative design maintains exceptional channel balance while minimizing signal degradation, allowing the UD-701N to perform as a true high-end analog preamplifier. Built for Serious Headphone Listening The integrated TEAC-HCLD2 headphone amplifier provides outstanding current delivery and exceptionally low distortion. With balanced and single-ended headphone outputs, multiple gain settings, and premium analog circuitry, it drives everything from sensitive in-ear monitors to demanding reference headphones with confidence. RDOT-NEO Upsampling Technology TEAC's proprietary RDOT-NEO intelligently upsamples PCM audio up to eight times the original sampling frequency, creating smoother waveforms, greater detail, and a more natural listening experience while preserving the musical character of the original recording. Four Independent Power Supplies Unlike conventional designs, the UD-701N utilizes four independent toroidal transformers dedicated to the digital, analog, network, and control circuits. By isolating each section, electrical interference is dramatically reduced, resulting in lower noise, improved channel separation, and greater dynamic performance. Fully Balanced Dual-Mono Architecture Separate left and right signal paths maintain complete channel independence throughout the audio circuit. Combined with a fully balanced analog output stage, this design produces a wider soundstage, more accurate imaging, and exceptional musical realism. External Master Clock Support A dedicated 10MHz master clock input allows the UD-701N to synchronize with an external reference clock, further improving timing accuracy and enhancing overall sonic performance for the most demanding audio systems. Designed for Reference Systems Constructed with a rigid aluminum chassis, vibration-controlled construction, premium internal components, and TEAC's meticulous engineering, the UD-701N is built to deliver decades of reliable, reference-quality performance. RockOnAV's Take The UD-701N is much more than a network streamer—it's the digital heart of a reference-quality Hi-Fi system. By combining TEAC's proprietary ΔΣ Discrete DAC, advanced streaming platform, precision analog preamplifier, and powerful headphone amplifier into one chassis, it eliminates the need for multiple separate components without compromising performance. When paired with the TEAC AP-701 Stereo Power Amplifier, it delivers a level of transparency, musicality, and control that rivals far more expensive separates. For listeners seeking a premium all-in-one digital front end, the UD-701N is one of the finest components in its class.
