The Topping E70 Velvet is a desktop DAC and preamp built on AKM's AK4499EX, with USB (XMOS XU316, up to 32-bit/768kHz and DSD512), coaxial, optical and Bluetooth 5.1 LDAC inputs feeding balanced XLR and RCA outputs. It suits desk and hi-fi systems that run a headphone amp, powered speakers or a power amp.
Who the Topping E70 Velvet is for
Powered speakers and power amps: In preamp mode the volume runs from -99dB to 0dB by knob or the included remote, so it can feed active monitors or a power amp directly.
Computer audio: The XMOS XU316 USB input plays PCM up to 32-bit/768kHz and native DSD512, plug-and-play on Windows 10/11, Mac, Linux, iOS and Android, with a driver needed only for Windows ASIO apps.
Streaming from a phone: Bluetooth 5.1 on a Qualcomm QCC5125 receives LDAC, aptX Adaptive, aptX HD, aptX LL, aptX, AAC and SBC, and the AK4499EX does the decoding.
Disc players, set-top boxes and amps: Coaxial and optical inputs take PCM up to 24-bit/192kHz, and the 12V trigger in/out switches it on and off together with a trigger-equipped amplifier.
Skip it if: You want to plug headphones straight in; it has line outputs only (XLR and RCA), so it needs a headphone amp, powered speakers or a power amp.
