About the TEAC UD-701N USB DAC/Network Player
The TEAC UD-701N USB DAC/Network Player is a serious step into reference digital playback.
What makes this unit truly special is that it does not use a conventional DAC chip. Instead, TEAC has developed a fully discrete DAC architecture using FPGA-based processing, which allows far greater control over conversion and sound tuning.
At its core is TEAC’s newly developed ΔΣ (Delta Sigma) discrete DAC, offering exceptional resolution, low noise and precise signal conversion for both digital and streaming sources.
The result is a presentation that is exceptionally clean, spacious and natural, with outstanding detail retrieval and imaging. Add to that its network streaming, preamp functionality and balanced design, and you have a component that can genuinely replace multiple boxes in a high-end system.
Frequently Asked Questions
