The world of desktop audio has seen a remarkable evolution, and the TOPPING E70 is a shining example of how far mid-priced DACs have come. With its exceptional components, solid build quality, and a refreshing tonal shift from its predecessors, the E70 stands out not just for how well it measures, but for how good it sounds.

The E70 is the flagship model of Topping’s E-Series DAC lineup. It comes in two versions: the standard E70 using the ESS ES9028PRO chip, and the E70 Velvet using the AKM 4499EX chip. This review focuses on the ESS-based version, known for its dynamic and engaging presentation.

Design and Build

The E70 features a minimalist aluminum chassis in black or silver, with a red-accented knob on the black version. It shares design elements with other E-Series models but has a slightly larger chassis to accommodate the internal power supply and full-size XLR connectors.

On the front panel, there’s a monochrome OLED screen, a touch-sensitive input selector, and a multifunctional rotary knob. The build quality is excellent, with clean lines and a modern, understated appearance.

Sound Impressions

Topping’s earlier DACs were often described as clinical or analytical. The E70 marks a shift toward a more musical and engaging sound. Its tuning offers a bold, full-bodied presentation with rich mids and deep, punchy bass. High frequencies are slightly relaxed, resulting in a warm but still detailed listening experience.

Bass and Midrange

The sub-bass and mid-bass are slightly elevated, providing a warm foundation without overwhelming the mix. There’s excellent slam, texture, and control. Vocals and instruments sound rich and natural, with a three-dimensional feel that puts them in the room with you.

Treble and Air

The treble has good extension and clarity, revealing subtle room reverb and microdetails, though it takes a slightly smoother approach than more analytical DACs. This leads to a fatigue-free experience that still preserves detail and nuance.

Soundstage and Imaging

The E70 presents a wide and deep soundstage, with excellent instrument separation and accurate imaging. Layering is handled well, and the overall spatial presentation is immersive. These qualities make it suitable for both audiophile listening and professional monitoring.

Bluetooth Performance

Bluetooth 5.1 connectivity is stable and surprisingly capable. The E70 supports LDAC, aptX HD, and more, offering near-wired quality when streaming from compatible devices. Real-world performance is smooth, with no signal drops even across rooms.

Comparisons

SMSL SU-9 Pro
Offers more treble energy and air, but costs around $150 more. The E70 delivers fuller mids and a warmer signature.

SMSL M500 MK2
Very close in quality. The E70 leans warmer and richer in the mids, while the M500 MK2 has more top-end sparkle.

Topping E50
The E70 is a significant upgrade in imaging, dynamics, and musicality. The E50 is flatter and more neutral, but lacks the depth and impact of the E70.

Pros and Cons

Pros

• Engaging, musical tuning with rich midrange
• Strong technical performance
