Topping A70 Pro Fully Balanced Headphone Amplifier for Audiophiles with Relay Volume Control and Remote(Silver) Toppin

In-Depth Feature Sheet

Re-Optimized new circuit architecture: - Newly Developed Ultra-Low Noise Input Stage: The ultra-low noise input stage significantly enhances noise performance for balanced inputs and boosts input impedance to 20kΩ, ensuring better compatibility with various incoming devices. - Redesigned Gain Architecture: The gain architecture has been thoroughly redesigned to minimize noise and distortion at high gain states, offering superior performance compared to the previous architecture.

Ground Loop Noise, Disappearing Magic: - When multiple devices are used in combination, ground loop noise can cause issues. The A70 Pro includes a GND/LIFT switch. By switching to LIFT mode, ground loop noise disappears, ensuring clean and clear audio playback.

Aurora UI, Bringing a New Experience: - Full Color Screen and Three Touch Buttons: Aurora UI features a vibrant full-color screen with three intuitive touch buttons, providing a new level of user experience. You can customize the display to show playback information, FFT, or VU meter as needed.

Relay Volume Control: - The A70 Pro utilizes relays and resistor networks to form an R2R volume control module. This ensures precise volume control, long service life, and stable performance even at very low volume levels.

A Headphone Amp, Also a Preamp: - The A70 Pro excels as a headphone amplifier while also serving as a versatile preamp. It maintains high performance in headphone amp mode, with an RCA output impedance of only 500Ω and an XLR output impedance of just 100Ω. This allows seamless compatibility with a wide range of input impedances, making it suitable for various power amplifiers. Additionally, a full-featured remote control simplifies operation, ensuring ease of use.
