Topping A70 Pro Fully Balanced Headphone Amplifier 17000mW*2 Relay Volume Control Pre Amp with Remote Control(Black)

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 20kΩ 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. Ground Loop Noise，Disappearing magic： 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，bring new experience： Full color screen and three touch buttons Experience has changed since.Colors Jump out at you The display of the playback information, FFT, VU can be switched according to your requirements. Relay volume control: A70 Pro uses relays and resistor networks to form R2R volume control module, which providing precise volume control, long service life, and will not deviate even at low volume. A Headphone Amp, also a Preamp: The A70 Pro drives headphones well, and it can also be used as a preamp. It has the same high performance as the headphone amp mode, with an RCA output impedance of only 500 and an XLR output impedance of only 100Ω, allowing it to be used with a wide range of input impedance for various power amplifiers. In addition, a full-featured remote control makes operation even easier. Headphone Amplifier SPEC:
