Cypher Labs Theorem 720 Headphone Amp USB DAC Fully balanced headphone amplifier.
Large capacity battery charges Apple devices while playing up to 18 hours.
Purchased as demo unit from Moon Audio in March; all accessories and perfect condition (see photos – note that USB female A to USB male mini-A adapter is included but didn't make the photo).
My listening habits have changed so this needs to move on.
