Apos Ensembles are equipment bundles that have been specially curated by our team of audio professionals. Just as an ensemble refers to a group of musicians playing together, each of our ensembles is a coordinated group of equipment that we’ve brought together to form a superior listening experience. 


Meet the TOPPING-90 Series Ensemble

The TOPPING-90 Series Ensemble is a supergroup of performers. The Topping D90 DAC and the Topping A90 work in perfect harmony, decoding and driving music above a pitch-black backdrop. A Fanmusic C006 XLR cable connects the two with pure-copper clarity. 


Accompanying them 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.
