Topping A70 Pro is a brand new high-power headphone amplifier designed with premium quality audio components. The amplifier delivers a whooping output power of up to 17000mW through the balanced output port, it can easily drive any headphone on the planet with its ultimate output thrust. The A70 Pro has a fully-balanced architecture with Topping̢۪s latest T̢۪ang-ku-la module design. Tang-ku-la means a mountain that an eagle cannot fly over. It symbolizes the spirit of Topping, climbing the peak, and benefits from the ultimate performance of the Tang-ku-la module. Add the E70 Pro to your desktop chain and greatly enhance the strengths of your chain with ultimate amplification!!

Topping̢۪s New T̢۪ang-ku-la Module:-

Topping A70 Pro promises top-quality sound signal amplification with its latest developed T̢۪ang-ku-la module. It adopts a new three-stage feedback circuit that greatly reduces noise and high-frequency distortion. This new technology also reduces heat generation, greatly improving reliability and extending the electronic component life.

Reoptimized Circuit Architecture:-

Topping A70 Pro features a newly-developed ultra-low noise input stage which further improves the noise performance of the balanced input. It also increases the input impedance of 20kΩ which improves its compatibility with other devices. Topping has also redesigned the gain architecture to further reduce noise and distortion at high-gain settings.

Expandable Inputs With External EXT90 Support:-

Topping A70 Pro supports a set of balanced XLR and Single-Ended RCA inputs. But users can expand the connections with the help of an external input device such as the Topping EXT90. With EXT90 connected to the A70 Pro, users get four Balanced XLRs and two single-ended RCA inputs.

Precise Volume Adjustment With R2R Relay Control:-

Topping has designed a precise volume adjustment system for the A70 Pro. The device uses relays and resistor networks to form an R2R volume control module. It provides precise volume adjustment with long service life and you won̢۪t get any deviation even at low volume levels.

Innovative New Display Screen With Aurora UI:-

Topping A70 Pro features a colorful bright display screen with three touch buttons. It has an Aurora UI system that helps you customize the look of the device. It displays playback information, FFT, Vu meter, etc available easily by pressing the volume knob.

Super Powerful Output, Ultra-Low Distortion:-

Topping A70 Pro houses loads and loads of output power. It houses enough juice to drive even the most demanding set of headphones out there with an output power rating of 17000mW@16Ω of load. It produces a strong output thrust with ultra-low distortion and noise levels. The noise-level is as low as 0.2uVrms promising quality performance even with high-sensitivity Headphones.
