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 SMSL-8s Ensemble

The stars of the SMSL-8s Ensemble are the SMSL SU-8s High Resolution ESS DAC and SH-8s High Resolution Headphone Amplifier, a Bluetooth-receptive duo that delivers up to 32-bit music with total transparency. A Fanmusic C003 RCA cable brings them together with pure-copper clarity. 


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.
