SUPER-CLEAN POWER FOR YOUR HEADPHONES WITH A HIGH-PERFORMANCE NFCA AUDIO CIRCUIT
The Topping A30 Pro is embedded with the redesigned NFCA (Nested Feedback Composite
Amplifier) based audio circuit. This circuit is optimised for stellar performance with super-clean and crisp
output. The A30 Pro is equipped with 10xOPA1656 OP-Amp architecture and UHGF(Ultra High Gain Feedback)
technology to maximise the performance of the A30 Pro. The overall Total Harmonic Distortion + Noise (THD+N)
of the Topping A30 Pro is below 0.00006%. In other words, the Topping A30 Pro restores up to 99.99994%
original sound so you can enjoy your music at pristine quality.

CAPABLE OF DRIVING THE MOST POWER-HUNGRY HEADPHONES WHILE RETAINING THE DYNAMIC RANGE
Topping A30 Pro is an incredibly powerful headphone amplifier. It can power hard-to-drive headphones without any trouble. It outputs up to 6W at 16 ohms of load, 5.5W at 32 ohms, 840mW at 300 ohms, and 420mW at 600 ohms of the output load. Massie output power and margin bring excellent control ability and drive all the demanding headphones with ease. It supports both power-hungry headphones and sensitive IEMs while maintaining a clean audio signal. Thanks to its NFCA-based circuit and UHGF (ultra high gain feedback) technology, the A30 Pro delivers a stunning 145dB of dynamic range. This means that 145dB exists between the lowest and highest volumes of sound it can reproduce, resulting in exceptionally realistic playback.

CLASS-A OPERATION FOR HIGH IMPEDANCE HEADPHONE AND GROUND LOOP ELIMINATING TECHNOLOGY
When the Topping A30 Pro is paired to a headphone with an impedance greater than 250 ohms, it offers complete Class A operation, thanks to the ample quiescent current architecture. When multiple pieces of equipment are operating in conjunction, ground loop noise can occur. Ground loop noise most often manifests as a buzzing or humming sound, which is loud enough to damage speakers or headphones. The Topping A30 Pro solves this issue with a dedicated GND/LIFT switch on the rear panel. When in normal use, set the switch to GND. If you encounter ground loop noise, flick it to LIFT, which will change the ground point of the A30 Pro from its chassis to the equipment it’s connected to, eliminating the noise.



OFFERS A VARIETY OF CONNECTIVITY OPTIONS WITH THREE-STEP GAIN AND INPUT PASSTHROUGH
The Topping A30 Pro is designed to be compatible with various headphones and to enable this, it features 4-Pin XLR + 4.4mm and 6.35mm outputs. You also get RCA and XLR connections for the input stage. The inclusion of these outports allows you to connect virtually any headphone without compromising on functionality or quality. The Topping A30 Pro headphone amp provides Three-Step gain settings with -14dB, 0dB, and +14dB gain modes to switch for use with IEMs or high impedance and full-size over-ears. Just connect your headphones or IEM and leave the rest to the Topping A30 Pro desktop headphone amp. When powered down, the A30 Pro passes the input signal directly to RCA or TRS connections without applying amplification. This allows you to connect active monitors to the A30 Pro and benefit from an outboard DAC with pre-amp functionality without introducing another amp into the chain. This process is called Input Passthrough and elevates the functionality of the Topping A30 Pro tenfolds.




BEST PAIRED WITH THE TOPPING D30 PRO DAC FOR EXCEPTIONAL PERFORMANCE AND CLEAN AUDIO
If you're looking to add a high-quality DAC to your desktop setup with the A30 Pro, do consider the Topping D30 Pro. The Topping A30 Pro and D30 Pro share the exact spatial dimensions, making them easily stackable. At a combined 4” of height, they're modest enough to fit under a monitor, in a desk compartment, or on a space-restricted shelf. The D30 Pro offers an extremely low level of jitters for all kinds of inputs and allows you to utilise the input passthrough capability of the A30 Pro. The pair of Topping A30 Pro and D30 Pro is an excellent choice for the modern music lover looking for a setup that can do it all.
