Our take
A new and improved version of the popular TA-01, the xDuoo TA-01B DAC/amp can easily drive high-end headphones, packing a lot of power into a compact piece of gear. The 12AU7 tube brings some warmth to the sound signature, hitting the sweet spot between analytical reference and homemade hi-fi. Meanwhile, the dual Cirrus Logic CS4398 chips allow each channel to be processed independently, resulting in lower crosstalk and noise, and a cleaner overall performance. The RCA jacks pull double duty as input for the amp and output for the DAC, and the upgraded XMOS U8 USB interface makes for a more stable performance.
Product details
MULTI-FUNCTIONAL COMPACT TUBE AMPLIFIER
12AU7, the much-praised tube welcomed by super fans is used as the preamp. The post-amp uses a high quality transistor to amplify the power, enough to push any higher low impedance headphones or earphones. A 12V adapter is used as the power supply, which greatly reduces the size and weight of the tube amp. It's very appropriate to use at home or the office. Simply connecting to PC or any other players and you'll get high quality music.
XMOS U8 MORE STABLE AND FASTER
The USB digital receiver chip applies an XMOS U8 chip in asynchronous transmission mode supporting digital audio of 32bit/192kHz and DSD128.The DAC part applies 2 Cirrus Logic chips CS4398.
SUPPORTS ASIO, KS AND WASAPI MODES
Supports ASIO, KS and WASAPI modes and greatly reduces the delay and distortion.
TWO HIGH QUALITY CRYSTAL OSCILLATORS
Two high quality crystal oscillators are used as the clock power source respectively working in 44.4k and 48k frequency and their multifold sampling rates. The mode is automatically switched by the system guaranteeing that the local clocks do not intervene with each other and are able to work independently.
12AU7 TUBES TRANSISTOR BUF STRUCTURE
It applies 12AU7 tubes + transistor BUF structure. The combination creates the audio with both grace and sense of strength.
