Last year, TOPPING showcased the A30 Pro, D30 Pro in the China International Headphone Expo(CIHE) 2020, and has grabbed a lot of attention from the audio community, many audiophiles are following interest with these two products. Topping unveiled the price of these two products last week ,and now it is finally available for pre-order. 

A30 Pro is an upgraded version of the A30, which is already a very  desktop-grade headphone amplifier equipped with many rich features. Compared with previous version, A30 Pro comes with an extra 4-Pin-XLR output and Balanced input. It has a total harmonic distortion plus noise (THD+N) down to just 0.00006%, which means this device accurately restores 99.99994% of the original sound. A30 Pro also adopts TOPPING’s own NFCA (nested feedback composite amplifier) modules, similar to what is being used in the A90 and L30 headphone amplifier can provide excellent AC & DC performance. The ultra-low noise of 0.3uV is miles ahead of the competition, giving an absurdly high dynamic range up to 145dB and no audible noise and darkest background for the most sensitive IEMs.

With 3 step gain settings, A30 Pro can which can easily adapt to the huge sensitivity span from IEMs to high impedance and full size over-ears. A30Pro is designed with ample quiescent current. When the headphone impedance is greater than 250 ohms, it will fully work in Class A operation. 2x6W@ 16ohm, 2x5.5W@32ohm, 2x840mW@300ohm, so there is no headphone that A30Pro can't drive well.

D30 Pro is the best DAC for A30 Pro, D30 Pro shares the same spatial dimensions with A30 pro, making them easily and perfectly stackable. D30 Pro comes with a quad DAC, 4 x CS43198 provide a total of 8 full balanced channels. So each channel of the D30Pro will be arranged in parallel by 4 conventional balanced channels. The increase in output capability will bring changes in the sound and the spec will also improved. It uses 2nd generations 8 core XMOS XU208, USB supports up to PCM32bit 384kHz and DSD256 native. With the help of customized Thesycon driver(for Win 7 or above), your PC will have better performance on ASIO playback.(Mac needn't a driver to achieve ASIO). 

D30Pro has preamplifier function so you can control the output volume on the front panel and also at the remote control. Since it's noise is <0.9uVrms@SE out and <1. 1uVrms@BAL out, which is significantly lower than other similar products, it is very suitable for connecting to power amplifiers or monitor speakers. And this will also help you leave the budget of a pream-plifier.
