{"type":"firestarter.listing","listing":{"id":"lst_p8z5Cukr","product_name":"xDuoo TA-22 DAC/Tube Amp","category":"Headphone Amp (Tube)","description":"The next generation of xDuoo DAC/Amps\nThe TA-22 is a desktop DAC and balanced tube headphone amplifier that provides high performance USB, optical, coaxial, and Bluetooth 5.1 audio decoding. Combining an XMOS XU208 USB chip and dual ESS D/A chips, the TA-22 supports PCM 32-bit/384kHz and DSD256, as well as MQA rendering. Connect your laptop, phone, or tablet via Bluetooth 5.1 and enjoy audiophile-grade Bluetooth codecs, like LDAC and aptX HD. \n3000mW balanced output\nPlug in your balanced headphones into the 4-pin XLR and 4.4 balanced outputs to enjoy up to 3000mW of output power. This much power can easily drive headphones with impedance from 16-600Ω.\nBluetooth 5.1\nThe TA-22 supports high-end Bluetooth 5.1 codecs like LDAC, Qualcomm aptX, and aptX HD. With playback support for 24-bit tracks and transmission up to 50 feet away, it’ll help you cut cords without sacrificing quality.\nDual ES9038Q2M DAC chips\nTwo ESS SABRE DAC chips process the left and right channels independently. These 32-bit audiophile-grade DAC chips decode 32-bit/384kHz PCM audio with a signal-to-noise ratio of up to 118dB.\nTube + transistor hybrid amp structure\nUsing a hybrid amp structure, the TA-22 offers the best of both tube and transistor worlds. With strong output power, the transistors can drive any sort of headphone, while dual 12AU7 tube amplification provides musicality, warmth, and smoothness.\nJapanese capacitance\nThe TA-22 uses a series of Japanese ELNA and NICHICON capacitances, which give the TA-22 a smooth and warm presentation with transparent high frequencies. \nProduct highlights\n\nBalanced output\nHD Bluetooth\nES9038Q2M x2 D/A chips\nTube amp\nOLED display\nDSD256\nPCM 32-bit/384kHz\nMQA 32-bit/384kHz renderer\n3000mW output power\n\nSpecs\n\nScreen: 3.2” OLED\nPower Supply: (AC100-120V/220-240V)\nCompliant OS: Linux, Window, MacOS, IOS, Android\nSampling Rate Support of USB IN:\n\nPCM: 16-32Bit/44.1-384kHz\nDSD: DSD64-DSD256\nMQA(Renderer): 44.1-384kHz\n\nSampling Rate Support of OPT/COAX IN:\n\nPCM.
