Topping E70 adopts ESS SABRE flagship DAC ES9028PRO, which has a 32-but 8-channel HyperStream II architecture. In the Topping E70, every 4 channel are connected in parallel as one channel, achieving high performance and sound quality, with ultra-low THD+N and high SNR ratings.
Brand new I/V conversion circuit Topping designed a brand new I/V conversion circuit to achieve better quality audio reproduction, lower distortion and lower noise while occupying less space.
LDAC 24bit96kHz Bluetooth transmission The Topping E70 has the certification of Hi-Res Audio Wireless and LDAC. It uses the newest QCC5125 chipset to support LDAC/AAC/SBC/aptX/aptX LL/aptX HD/aptX Adaptive protocol by Bluetooth 5.1. To get even better sound quality from Bluetooth, we abandon the buit-in DAC QCC5125 and connect its digital signal to ES9028PRO to decode.
Newest XMOS XU136 USB processor USB input of Topping E70 has a wide range of compatibility: Windows 10, Windows 11, MAC, Linux, iOS, Android and it is plug and play. Only for Windows ASIO applications, you need to install the driver and set it up. The USB hardware is based on the newest XMOS XU136 and Thesycon custom driver (applicable to Windows; other systems are driver-free), which is stable and reliable.
Coaxial and Optical (Toslink) The optical and coaxial input of Topping E70 supports up to PCM24bit192kHz and DSD Dop64 audio, which is suitable for digital turntables, disk players or game consoles.
Auto On/Off function The Topping E70 has an automatic On/Off function. That means that it will automatically turn on and set to the input whenever a valid signal is provided. When the signal of the active input is not active for 1 minute, the Topping E70 will turn off automatically.
12V Trigger interface The Topping E70 is equipped with a 12V Trigger interface, which has both active control and passive control. With a 3.5 mm to 3.5 mm cable, the Topping E70 can bue turned on and off synchronously with other devices equipped with a 12V Trigger interface. This is really convenient, especially when used with amplifiers, like L70.
Selectable XLR+RCA output options The Topping E70 has balanced XLR output and single-ended RCA output ports. You can easily choose “XLR only”, “RCA only” or “XLR+RCA” output. The level of the XLR output can be changed from 4V to 5V and RCA output can be changed from 2V to 2.5V.
Preamplifier function In addition to the DAC mode with a fixed output level, the Topping E70 also has a DAC+preamplifier mode. In this mode, you can control the output volume from -99dB to 0dB by the knot or by the remote control.
