Apple made no announcement that Apple would support 24bit/96kHz and Mashable confirmed this with some testing here! So... No, the iPhone 6 Doesn't Play High-Res Audio yet. Maybe the iPhone 6s and 6s plus will support HD audio. Is it possible that apple will update iOS 8 with support for HD audio? It's possible. Apple is preparing to enable high-definition 24-bit downloads from iTunes. The audio hardware inside the phone may be capable of 24bit/96kHz output. According to teardown analyses, Apple's iPhone 6 includes the custom made Cirrus Logic 338S1201 chip, which is likely the successor to the Cirrus Logic CS42L61 chip used in previous iPhone models. Though also a custom build, the older CS42L61 chip is part of Cirrus Logic's CS42L51 family, which supports 24bit/96kHz HD audio.
