Meet the TOPPING DX7 Pro Ensemble

The star of the TOPPING DX7 Pro ensemble is the TOPPING DX7 Pro, a DAC/amp that delivers a stunning performance with its flagship ESS DAC chip.

Accompanying it is one of three pairs of headphones: the Meze Audio Empyrean Open Back, the Dan Clark Audio Æon 2, or the QUAD ERA-1 Planar Magnetic. The Empyrean dazzles with state-of-the-art comfort, warmth, and incomparably sweet mids. The Æon 2 delivers a spotlit performance with its vast soundstage and micro-detail retrieval. The QUAD ERA-1 captivates with rapid, clarified bass and impeccable transparency.
