Samsung Galaxy S7 may offer best audio in a smartphone
According to these reports from MyDriver.com, via TechRadar, Samsung will utilise the SABRE 9018AQ2M chip from ESS Technology that should offer the best audio in a smartphone.
The chip supports formats like DSD, features a 32-bit mobile audio DAC, and has 129 dB signal to noise ratio. This all means that you should have a listening experience akin to listening to analogue, but while streaming audio over the internet.
