New to streaming question

Hi - I'm an analog front end guy but recently decided to start streaming in our family room.  I have a Naim Uniti Atom HE and have been using Quboz to stream but have a simple question.  The Hi-Res files on Quboz albums are available in 24bit-192 however the maximum I can play is at 24bit-92.  I have a CAT8 wired from my router directly to the Naim and am using my phone with Quboz to stream to the Naim via Chromecast.  What do I need to do connection-wise to listen to the files in 192?  Apologies for the basic question, I'm new to the streaming world.  Thanks very much
