According to several insiders familiar with Apple, whose products
are exhibited at PORTABLE AUDIO FESTIVAL
2015, the company has been developing
Hi-Res Audio streaming up to 96kHz/24bit in 2016.
The Lightning terminal with iOS 9 is compatible up to
192kHz/24Bit, but we do not have information on the sampling
frequency of Apple Music download music.
Also, many high-end audio manufacturers plan to add audio cables
for Lightning to their lineups in 2016, and they apparently are
preparing themselves for Apple Music’s Hi-Res Audio.
Yet another indication that the analog headphone jack might be a goner.
