xDuoo TA-32 | DAC + Tube Balanced Headphone Amp

xDuoo TA-32 High-Performance DAC and Balanced Tube Headphone Amp Features Class-A Amplification, USB, Optical, COAX, Bluetooth 5.1, and a Replaceable DAC Card Design  Successor to the xDuoo TA-22 DAC and Amp Powerful amp with up to 3000mW power over 4.4mm and XLR ROHM BD34301 DAC chip for low distortion and high resolution Recommended for headphones with impedance of 16-600Ω Tube rectification (5U4G) and matched pair of Ray Tubes 12AU7 CORE for the audio stage Highlighted Features Balanced Output up to 3000mW The TA-32 is a Class-A hybrid headphone amplifier for listeners who appreciate a bit of tube warmth paired with the punch of solid-state circuitry. With 4-pin XLR and 4.4mm balanced outputs, up to 3000mW of power can be achieved, easily and beautifully driving headphones with an impedance tolerance of 16-600Ω for more details in all frequencies. USB DAC Decoding TA-32 supports USB decoding with connection to computer, mobile device (iOS + Android), tablet, HiFi audio player, and other devices. Optical + COAX Decoding Coaxial and optical fiber decoding is supported with various desktop or portable players with the adoption of the AK4118 receiver chip, supporting up to PCM 24Bit/192kHz + DSD64. Bluetooth 5.1 The TA-32 weighs in with Bluetooth 5.1 using Qualcomm's QCC5125 chip. SBC, AAC, aptX, aptX LL, aptX HD, and LDAC are all supported. Analog Tube Warmth A 5U4G vacuum tube handles rectification, while a pair of matched Ray Tubes 12AU7 CORE lend classic tube characteristics to the midrange and treble; and a Class-A transistor stage supplies a steady flow of current. This marriage of classic tube sonics and modern power delivery produces a signal that’s as warm as it is detailed.  Swappable DAC Card  TA-32 uses a replaceable DAC module so you can enjoy different DAC cards without having to purchase an entirely new DAC/Amp. The chip included with the TA-32 is ROHM's flagship BD34301 chip. This chip boasts low distortion, higher SNR, greatly improved resolution, and more detailed sound performance. Enthusiast Capacitance Customized metal polyester film capacitors are used for duct output, complete with enthusiast-grade Japanese ELNA capacitance for coupling, resulting in a transparent and sweet sound. Enthusiast-grade Japanese NICHICON was chosen for the main filter capacitance for smoothness and superb high-frequency.
