xDuoo TA-01B 12AU7 Tubes AMP High Performance HIFI USB DAC Tube

Product description:   MULTI-FUNCTIONAL COMPACT TUBE AMPLIFIER 12AU7, the much-praised tube welcomed by super fans is usedas the preamp.The post-amp uses a high quality transistor toamplify 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.
