Oppo Digital — not to be confused with phone maker (and sister company) Oppo Electronics — has quickly made a name for itself as a top audiophile brand. Oppo’s high-end Blu-ray players have set a new bar for both audio and video performance, and the company’s transition into the advanced field of planar magnetic headphones last year has put it in some rarified company, competing well with the likes of Audeze, HiFiMan, and others.
