HiFiMan & Oppo
Also on hand in the Ultra Systems/Cable Company room was the HiFiMan EF6 ($1599), seen here atop an Oppo BDP-83 modified by Exemplar Audio ($2500). We first saw the EF6 at CES. The 5W, solid-state, class-A design is HiFiMan's answer to the most difficult-to-drive headphones. The Exemplar Audio-modded Oppo has a new linear power supply, upgraded op-amps, and high-quality polypropylene capacitors.
