A pleasant to the eye, the ear, and the hands

The birth of E70V marks the return of AKM flagship AK4499EX decoder, with a known reputation for low-distortion and high-definition music. Thanks to its incredible chips and the low noise Vref, E70V is able to accurately represent every detail in the audio with ultra-low jitter and a THD+N as low as 0.00006% (A-weighted). The distortion is minimized to -125db while the noise is only less than 1.3uVrms. What’s more, with attention paid to details, the E70V is aesthetically designed with a sleek and artistic exterior, that feels well and responds to commend in a speedy and satisfying manner.

LDAC 24bit/96kHz Bluetooth Transmission

Japanese Hi-Res Audio, Hi-Res Audio Wireless, and Sony LDAC certified, the E70V supports input in LDAC/AAC/SBC/aptX/aptX LL/aptX HD/aptX adaptive protocol via Bluetooth 5.1, thanks to its latest QCC5125 chipset. What contributes the most to this powerful chipset is the introduction of the AK4499EX, which replaced the original DAC of the QCC5125 and take the performance of E70V to the next level.

Wide Compatibility With Wired Input

With the latest XMOS XU316, the USB port on E70V support Win10/11, Mac, Linux, IOS, Android, and even Win ASIO with an app installed. The connection for all devices are stable and reliable, with DSD512 and PCM768kHz supported. Other than the USB port, E70V also has coaxial and optical (Toslink) ports that support up to 24bit/192kHz audio, allowing you to have a new perspective of traditional equipment such as digital turntables, disk players, and set-top boxes.

XLR and RCA ports for various types of output

With balanced XLR output and single-ended RCA output on offer, the E70V support either XLR or RCA output and the combined mode. And additionally, in the combined mode, you can choose either XLR 4V + RCA 2V or XLR 5V + RCA 2.5V, for more devices adapted or for greater performance.

Decoder and low-noise Amplifier

The E70V offers two modes, the DAC mode with a fixed electrical level and the Preamplifier mode. With the latter turned on, the E70V can output volume from -99dB to 0dB, saving you the budget of getting a preamp to work in a set with a power amplifier or monitor speakers.

Recommending L70 as the best amplifier for E70V

With the same design concept, L70 will be the perfect match for E70V as a well-suited amplifier for most headphones and earphones. With the 12V Trigger ports, both L70 and E70V can be turned on/off synchronically with either device.

12V Trigger Interface

E70V is equipped with a 12V Trigger port, allowing E70V to synchronously power on or off with other devices whether the commend comes from E70V or the other device. Simply connecting E70V with the other device with a 3.5mm to 3.5mm cable, and the two devices can be turned on/off as one.
