TOPPING E70 Velvet High-Performance DAC - Clear, Low-Noise Sound

In this review the TOPPING E70 Velvet is presented for listeners who want studio-level clarity without an overly complex setup; its single biggest reason to buy is the combination of ultra-low noise and flexible outputs that make it both a precise desktop DAC and a convenient preamplifier. The E70 Velvet's -125dB distortion floor and 1.3uVrms noise performance translate to an exceptionally quiet background, while Bluetooth 5.1 LDAC and a USB XMOS input support modern streaming and high-resolution files in a single compact unit.

Key Features

• Ultra-low distortion: The low-noise voltage reference power supply yields an exceptionally clean output for detail retrieval and low background noise.
• High-resolution USB support: XMOS XU316 USB input accepts DSD512 and PCM768kHz for native playback of demanding digital files.
• Bluetooth 5.1 with LDAC: QCC5125-based wireless lets listeners stream high-res audio that is digitally forwarded to the AK4499EX DAC for consistent quality.
• Selectable outputs and preamp mode: Switch between fixed DAC output or adjustable preamplifier volume, and choose balanced XLR or single-ended RCA outputs to suit different systems.
• Auto on/off and 12V trigger: The unit powers on with a valid signal and offers a 12V trigger for synchronized power control with compatible components.
• Low THD+N design: Measured THD+N of less than 0.00006% (A-weighted) preserves transient detail and imaging fidelity.

Who It's For

The E70 Velvet is ideal for serious listeners and desktop audiophiles who want a compact DAC with both high-resolution wired inputs and modern wireless convenience; it suits those pairing a DAC with powered monitors, a separate amplifier, or a small stereo system. The selectable output levels and preamp function make it useful as the central control device for an entry-level two-channel rig.

Buyers who prefer a purely analog input path or need an integrated streamer with apps may want to look elsewhere, since the E70 focuses on digital conversion and does not provide onboard network streaming or extensive room-correction features.

Pros & Cons

Pros

• Exceptional low-noise performance and very low distortion deliver clean, detailed sound.
• Flexible I/O with USB supporting DSD512/PCM768kHz plus coaxial and optical inputs covers most digital sources.
• Bluetooth 5.1 LDAC support offers convenient high-res wireless streaming to the AK4499EX stage.
• Preamplifier mode and 12V trigger simplify integration with other components.

Cons

• The user interface receives mixed feedback from customers and may take time to get used to.
• No network streaming or native app control, so users wanting an all-in-one streamer amp should consider other options.
