SPL's Phonitor X headphone amp includes a crossfeed mode designed to keep the soundstage in front of you, rather than in your head.

Audioengine says its new HD3 is more than just a warmed over version of its famous AE2. It is not only an active mini-monitor but can also function as a headphone amp.

Not every stereo integrated amp has the advantage of Anthem Room Correction.

"When Harman, Datasat, BMW, Volvo, Pioneer, Arcam, Emotiva, Xiaomi, Oppo, and OnePlus want digital audio optimization solutions, they turn to Dirac," boasted a sign at the Dirac exhibit. But the demo was not of the Swedish company's world-beating room correction systems but of a newly developed system to enhance headphone listening for virtual reality and gaming.
