Newbie Help Shure HD 535 Earbuds Astell&Kern KANN DAC HELP

Hello All,

First post and question

I have a set of Shure SE535 earbuds with an iPhone X /3.5mm OEM DAC/Amp cable using the HIFI Tidal streaming service.

Since the IPhone X can support LossLess formats would I obtain any appreciable benefit by using an external  dedicated combined amp/DAC  such as the Astell and Kern KANN Hi Res Music Player?

Confused in Maryland, Steven
