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-50s Series Ensemble
The TOPPING-50s Series Ensemble is a supergroup of performers. The Topping D50s DAC and the Topping A50s amp work in perfect harmony, decoding and driving music above a dizzyingly low noise floor. A TOPPING P50 power supply supplies ultra-quiet energy in a stackable aluminum chassis, while a Fanmusic C003 connects the DAC and Amp.
Accompanying them is one of seven pairs of headphones. Although any of these headphones will prove an excellent complement to the ensemble, they represent different price points and sound signatures, so we invite you to explore their product pages for more information.
The TOPPING-50s Series Ensemble Includes
DAC: Topping D50s DAC
Power Supply: TOPPING P50 Linear Power Supply
Interconnection: Fanmusic C003 RCA cable to connect the DAC and Amp
