Topping continues to refine its compact DAC lineup with the introduction of the Topping E50 II, an updated version of one of the brand’s most popular digital-to-analog converters. Designed for both desktop use and integration into traditional hi-fi systems, the E50 II builds on the strengths of its predecessor while introducing new processing features, broader connectivity, and enhanced user control.

The DAC is powered by an AKM AK4497S chip from Asahi Kasei, while the USB interface is implemented with an XMOS XU316 processor, designed to ensure fast processing and high streaming stability.

At the heart of the E50 II is the AKM AK4497S DAC chip from Asahi Kasei, paired with an XMOS XU316 USB controller. This combination is designed to deliver fast data handling, stable USB performance, and high-resolution audio playback. The DAC supports PCM up to 32-bit/768 kHz and DSD up to DSD512, placing it firmly in the high-resolution category. Wireless streaming is also supported via an integrated Bluetooth module with LDAC compatibility, allowing high-quality audio playback without a physical connection.

Advanced Digital Architecture and Clock Control

Internally, the Topping E50 II employs a signal-processing architecture built around a proprietary FPGA platform, combined with a PLL-based clock generation system. Topping refers to this integrated solution as TopSync, while its jitter-reduction technology is branded JitterNull.

According to the manufacturer, this approach significantly improves clock synchronization and reduces timing errors across all digital inputs. In practical terms, users can expect consistently clean and stable audio performance, whether the signal is delivered via USB, optical, or another digital interface.

Automatic Input Detection for Hi-Fi and Studio Use

One of the standout features of the E50 II is its automatic detection of S/PDIF and ADAT signals on the optical input. The DAC identifies the incoming digital format and configures itself automatically, eliminating the need for manual input switching.

This functionality expands the E50 II’s appeal beyond traditional hi-fi systems. It can also serve as a compact DAC solution for musicians, content creators, or small production setups, where ADAT compatibility and fast signal recognition are valuable additions.

Built-In Parametric EQ and App Control

The Topping E50 II includes a built-in parametric equalizer (PEQ), allowing users to fine-tune the sound to match their personal preferences, room acoustics, or connected equipment. All adjustments are handled through the Topping Home mobile app, which also provides control over input selection and output volume.

This app-based control system makes the E50 II particularly attractive for desktop and minimalist systems, where physical controls are limited but precise adjustment is still desired.

Flexible Outputs and Preamp Functionality

Connectivity is another strong point. The E50 II offers both RCA outputs and a balanced stereo output via a 6.3 mm jack, with the option to use both simultaneously. This makes the DAC equally suitable for pairing with classic integrated amplifiers, active studio monitors, or headphone amplification chains.

Depending on the setup, the output can be configured for fixed-level DAC mode or variable-level preamplifier mode, giving the E50 II additional versatility in compact systems.

High-Quality Bluetooth Streaming

In addition to wired connections, the E50 II supports Bluetooth streaming with an extensive codec lineup, including SBC, AAC, aptX, aptX HD, aptX Adaptive, and LDAC. This ensures compatibility with a wide range of devices while maintaining high audio quality for wireless playback.

In addition to wired connectivity, the Topping E50 II offers Bluetooth connectivity with support for SBC and AAC codecs, as well as aptX, aptX HD, aptX Adaptive, and LDAC.

Price and Availability

The Topping E50 II DAC is now available in Europe at a price of €199. Buyers can choose between black, silver, or white chassis finishes, all featuring a black front panel for a consistent, understated aesthetic.

With its expanded feature set, refined digital processing, and flexible connectivity, the Topping E50 II positions itself as a highly competitive DAC for users seeking precision, versatility, and high-resolution performance in a compact form factor.
