TOPPING A70 PRO: The Reference-Grade NFCA Headphone Amplifier
The TOPPING A70 PRO is a flagship headphone amplifier engineered for maximum performance and versatility in a high-end desktop system. Utilizing an all-new NFCA architecture, the A70 PRO delivers immense power, an unparalleled low noise floor, and pristine sound quality, making it the definitive choice for driving the most demanding planar magnetic and high-impedance headphones.
New NFCA Architecture for Unrivaled Purity
The A70 PRO features an evolved amplifier circuit designed to achieve absolute technical transparency.
All-New NFCA Modules
The core of the A70 PRO is the latest generation of TOPPING’s NFCA (Nested Feedback Composite Amplifier) modules. This advanced, optimized design achieves stunning metrics, including a Total Harmonic Distortion plus Noise (THD+N) of less than 0.00005%, ensuring the amplifier is acoustically invisible and does not color the source sound.
Immense Power Output
The A70 PRO is a true powerhouse, capable of outputting over 17 Watts (17000mW) of power per channel into a 16Ω load. This extreme power capability ensures perfect control, dynamics, and bass response when driving any high-impedence or low-sensitivity headphone on the market.
Professional Connectivity and Flexible Routing
The A70 PRO is built to function as the central amplifier and preamp in a complex audio chain.
Full Balanced XLR and Single-Ended RCA I/O
The unit features both Balanced XLR and Single-Ended RCA input and output ports. This allows for seamless connection to any high-end DAC (like the D70 Pro series) and the use of the A70 PRO as a high-fidelity Preamplifier to drive active speakers or a dedicated power amplifier.
Three Selectable Gain Settings
With three selectable gain settings (Low, Mid, High), the A70 PRO offers the versatility to precisely match the amplifier's output level to the specific sensitivity of your headphones, ensuring maximum volume range and the lowest possible noise.
