Topping A70 Pro | Desktop Headphone Amp

Capture the Pinnacle of Music for Under $500 with Topping A70 Pro Fully balanced headphone amplifier with 17 Watts of power Topping designed T'ang-ku-la Module delivers incredible dynamic range with a low noise floor Aurora UI enhances the experience with a fluid interface design T'ang-ku-la Module T'ang-ku-la means a mountain that an eagle cannot fly over, the source of the Yangtze River. It symbolizes our spirit of climbing the peak and the ultimate performance of T'ang-ku-la module. The T'ang-ku-la Module uses a new three-stage feedback circuit. Further reducing noise and high frequency distortion, making the dynamic range rise to an unmatched 147dB new realm. The new technology greatly reduces heat generation, thus greatly improving reliability, extending electronic component life, and reducing thermal noise. Re-optimized New Circuit Architecture Newly developed ultra-low noise input stage further improved the noise performance of balanced input and increased the input impedance to 20kQ thus having better compatibility with incoming devices. The gain architecture has also been redesigned to further reduce noise and distortion at high gain states than the previous architecture. Relay Volume Control with Independent Volume Memory A70 Pro uses relays and resistor networks to form an R2R volume control module, which provide precise volume control, long service life, and are fully accurate and balanced across channels, even at low volume. This system combines with 8 volume presets that allow you to switch Make Ground Loop Noise Disappear When multiple devices are used in combination, ground loop noise may be encountered. A70 Pro adds a GND/LIFT switch, when ground loop noise is encountered switch to LIFT and the noise will disappear. Aurora UI Experience The full color touch screen and touch buttons enhance the user experience with A70 Pro. You can display playback information, FFT, and VU meters. Customizations are available with a simple press of the knob. Specifications In the Box A70 Pro Amplifier AC Cable 6.3mm to 3.5mm adapter A70 Pro User Manual Topping 1 year Warranty Card
