TEAC UD-701N Network DAC/Preamplifier with Discrete Delta Sigma Design Revolutionary TEAC ΔΣ Discrete DAC Instead of using a generic DAC IC, the UD-701N incorporates a newly-develo
ped TEAC ΔΣ (Delta Sigma) discrete DAC comprised of discrete circuitry using FPGA with original algorithms. This achieves a wide, perfectly clear sound field that represents TEAC reaching the pinnacle of its sound objectives. DSD signals transmitted as-is for ultimate purity PCM signals converted to 1-bit or multi-bit (user selectable) Supports 22.5MHz DSD and 384kHz/32-bit PCM playback ⚡ Dual Mono Structure Best-in-class dual mono design throughout with independent left and right toroidal core transformers, preventing channel interference for rich musical expression and dimensional soundstage. 🔄 Fully-Balanced Transmission Fully balanced transmission at every stage improves signal-to-noise ratio and dynamic range, conveying signals in their purest state without losing the sense of air inherent in high-resolution sources. 🔌 Four Toroidal Transformers Dedicated transformers for left/right analog, network module, and digital control sections ensure stable, interference-free power delivery. Linear power strengthens the network module for advanced processing. 🎚️ TEAC-QVCS Volume Control Quad Volume Control System with four independent circuits (L+, L−, R+, R−) and 0.5dB fine adjustment. Shortest possible signal path prevents degradation for pristine audio quality. Analog Preamplifier with Premium I/O Functions as both a USB DAC/Network player and high-quality analog preamplifier with comprehensive connectivity: Analog Inputs: 2 line inputs via RCA and XLR connectors Digital Inputs: 2× Coaxial and 2× Optical TEAC-HCLD2 Buffers: Enhanced-current output with diamond buffer amplifiers in dual-circuit structure Premium Headphone Amplifier 4-pin XLR headphone amplifier switchable between balanced and active ground. Four diamond buffers (L, R, +, −) enable true balanced drive with parallel operation for single-end use. Drives 600Ω high-impedance headphones with authority and finesse. MQA Full Decoder Master Quality Authenticated full decoder with 5ms precision waveform control achieves analog waveforms true to original recordings. Greatly reduces "sound blurring" during sudden transients and extreme dynamic shifts. Supports MQA from files, network streams, and digital inputs—including MQA CD playback when connected to a CD player's digital output.
