High-Resolution DAC Preamp

The Topping E30 II Silver is a DAC and preamplifier built around two AK4493S chips using AKM Velvet Sound technology. It accepts USB, coaxial and optical inputs and decodes PCM up to 32-bit/768 kHz and DSD up to DSD512. The unit provides full digital volume control and an LED display for status feedback.

Compact Build with Flexible Power

Measuring 10.0 cm by 12.5 cm by 3.2 cm and weighing 295 g, the silver chassis fits easily on a desk or shelf. It runs from a 5 V DC supply that can be sourced from a computer USB port, phone charger or power bank, with built-in protection against incorrect voltage. RCA line outputs connect to amplifiers or active speakers.

Upgrade Path for Digital Sources

The E30 II replaces a basic computer sound card or the internal DAC of an older AV receiver, adding high-resolution USB decoding and separate coaxial and optical inputs for disc players, streamers or game consoles. The jump is worthwhile when the source material exceeds 24-bit/192 kHz or when a dedicated preamp stage with remote volume control is needed.
