Meet the Matrix Element X Ensemble

The star of the Matrix Element X Ensemble is, of course, the Matrix element X. This DAC/Amp/streamer is an audiophile’s Swiss army knife, tackling nearly any home theater scenario. 

Accompanying it is one of six pairs of headphones: the Meze Audio Empyrean Open Back, the Dan Clark Audio Æon 2, the QUAD ERA-1 Planar Magnetic, the HIFIMAN Arya, the HIFIMAN, HE1000v2, or the HIFIMAN Ananda. 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. The Arya enthralls with rapid, clean low-end and airy, clarified high-end. The HE1000v2 stuns with its energetic and intimate sound signature. The Ananda mesmerizes with detail retrieval and image distinction.
