As one of China’s most technically advanced international competitive audio manufacturers, TOPPING provides numerous devices, including digital DAC, HP amplifiers, and Preamplifiers. And today, we’ll look at the mid-range stack of the 70 series, D70PRO SABRE, and A70PRO, coming in at $699 and $499 separately.
TOPPING D70 Pro SABRE DAC
It adopts the flagship decoding chip ES9039SPRO and 3rd generation XMOS XU-316 for achieving better performance. Besides, D70 Pro SABRE combines with the new IV conversion circuitry, which uses an exclusive design that provides lower distortion and noise while occupying a smaller volume.
The D70 Pro SABRE achieves a new level of musical reproduction capability with the finest details. It supports LDAC/aptX-Adaptive/aptX HD/aptX/AAC/ SBC audio encoding, allowing high-quality audio to be transmitted wirelessly for a better sound experience.
Meanwhile, D70 Pro SABRE has wide compatibility and can be used on multiple operating systems, such as Windows 10, Windows 11, MAC, Linux, and iOS/Android. It requires driver installation and setup for ASIO applications on Windows systems only. The USB hardware is based on XMOS XU316 and Thesycon custom driver (applicable to Windows, other systems are free of driver), which is stable and reliable.
In addition to the fixed output level DAC mode, the D70 Pro SABRE also has a “preamp” mode. In this mode, the D70 Pro SABRE can adjust the volume and output directly to the power amplifier or active speakers.
D70 Pro SABRE can memorize the output volume of “Single Ended”, “Balanced” and “All” modes respectively. And the next time the output is selected, it automatically reverts to the last used volume.
TOPPING A70 PRO AMP
As a fully balanced headphone amplifier, A70 Pro uses the T’ang-ku-la Module, further reducing noise and high-frequency distortion, making the dynamic range rise to 147dB. The new technology greatly reduces heat generation, thus greatly improving reliability, extending electronic component life, and reducing thermal noise.
The newly developed ultra-low noise input stage further improved the noise performance of balanced input and increased the input impedance to 20KΩ thus having better compatibility with incoming devices. The gain architecture has also been redesigned to further reduce noise and distortion at high gain states than the previous architecture.
A70 Pro uses relays and resistor networks to form an R2R volume control module, which provides precise volume control, long service life, and will not deviate even at low volume.
Same as almost the amplifier TOPPING made, A70 Pro also offers the GND/LIFT switch to cancel the ground loop noise.
Except for working as a headphone amplifier, A70 Pro can also be used as a preamp. It has the same high performance as the headphone amp mode.
In terms of the design language, A70Pro and D70Pro SABRE introduce the Aurora UI design, full-color screen, and three touch buttons for bringing a new experience. On the front panel, the volume knob can access the customized functions. Both can meet the needs of the vast majority of headphones and active speakers. The A70 Pro and D70 Pro SABRE can be switched on and off in conjunction via the 12V Trigger connector, allowing the A70 Pro to be synchronized with the D70 Pro SABRE for automatic or manual switching.
