8-channel DAC chip

The E70 uses the ESS SABRE ES9028Pro DAC chip, which boasts a 32-bit, 8-channel Hyperstream II architecture. In the E70, 4 channels are connected in parallel as one channel, achieving incredible power performance and sound quality. 

Brand new I/V conversion

The E7 uses a brand-new conversion circuit designed to provide lower distortion and lower noise while occupying less space. This allows the E7 to perform at 0.00006% THD+N in a chassis that’s shorter than 8” on its longest side.

Updated aesthetic

TOPPING has given the 70 line its own unique and updated aesthetic. Featuring a wide chassis, oversized potentiometer (with a striking red outline in the black version), and over-chamfered edges, it’s a stand-out piece of equipment that’ll look great wherever you place it.

24bit LDAC Bluetooth

Stream the absolute highest quality Bluetooth. Thanks to its QCC5125 Bluetooth 5.1 chipset, the E70 qualifies for Hi-Res Audio Wireless Certification, supporting protocols such as LDAC, aptX HD, and aptX adaptive. TOPPING didn’t stop there. To ensure the best Bluetooth sound quality, they rerouted the digital signal from the Bluetooth chip to the ES9028Pro DAC chip, allowing the ESS chip to decode the BT signal at the absolute best quality.

Widely compatible

The XU316 USB controller chip makes the E70 plug-and-play compatible with Windows 10, Windows 11, Mac, Linux, iOS, and Android. A driver is only required for Windows ASIO applications.

Give your sources new life

Plug in your turntable, CD player, TVs, and game consoles into the E70 via optical or coaxial. Supporting 24bit/192kHz PCM and DSD DoP64 audio, the E70 will breathe new life into your favorite sources.

Auto on/off function 

When the E70 recognizes an input signal, it turns on and sets itself to the recognized input. When it doesn’t receive a signal for sixty seconds, it automatically shuts itself off.

12V trigger interface

The E70 comes with a 12V trigger on the back panel. This simple jack lets you create a network between any units that also feature a 12V trigger. When connected, it makes one product control the power of the other products in the system. When you turn on one unit, the rest of the system comes on automatically.

Pre-amplifier mode

The E70 doubles as a preamplifier, allowing you to control the output volume of destination monitors on its front panel or with the included remote control from -99dB to 0dB.
