TOPPING E50 II Hi-Res DAC with App Control — XMOS USB, DSD512/PCM768kHz, LDAC BT (White)

Meet the TOPPING E50 II: a compact, high‑fidelity DAC and preamp you can steer from your phone

The TOPPING E50 II blends premium digital-to-analog conversion with practical control features that fit real listening rooms. It focuses on clarity, musical detail, and flexible integration, so you can tailor the signal path to your gear and tastes without complicating your setup.

Smartphone-powered control puts input/output routing, volume, and a full parametric EQ at your fingertips. The integrated app lets you manage your entire audio chain in real time, keeping you in the moment of the music rather than juggling controls on a device nearby.

High‑resolution USB playback supports PCM up to 768 kHz and native DSD up to 512, with MQA decoding for compatible files. The USB path is designed for broad compatibility across Windows, macOS, Linux, iOS, and Android, offering a plug‑and‑play experience for most systems and a responsive, low‑latency workflow.

DAC and preamp, with flexible outputs offer selectable operating modes and both RCA and TRS outputs. You can choose your preferred output level and use touch controls or a remote for convenience, enabling a clean handoff to an integrated amp or powered speakers.

Signature USB performance comes from a flagship XMOS USB engine that supports DSD64–DSD512 (Native) and DoP, plus PCM up to 768 kHz/32‑bit. This combination is designed to deliver accurate timing and wide dynamic range, helping music breathe with intent and space.

Tuning at your fingertips includes a built‑in 10‑band parametric EQ with independent left/right adjustments and the ability to import target curves. Save multiple user profiles for different listening rooms or genres, and switch between them as needed.

Smart optical detection analyzes dual‑format optical inputs to identify S/PDIF or ADAT formats automatically, covering common home and professional workflows. This helps reduce setup friction when you’re connecting multiple sources.

Low jitter for cleaner timing is delivered by FPGA and PLL TopSync circuitry with JitterNull technology, designed to minimize timing errors and preserve musical detail across digital paths.

Wireless high‑res option via Qualcomm QCC5125 Bluetooth includes LDAC, aptX Adaptive/HD, AAC, and SBC, enabling high‑resolution wireless streaming up to 96 kHz / 24‑bit where a stable connection is available. This adds flexibility for casual listening or mobile setup, without sacrificing core audio performance.

In practice, the E50 II aims to be a versatile centerpiece for a modern listening space—one that respects your source quality, offers tangible control, and provides room to refine tone and balance. While results depend on your gear and room, the combination of robust USB decoding, flexible outputs, and precise EQ can help you approach a listening experience that feels clear, coherent, and engaging.
