I’m currently using an 11in iPad Pro (A12 chip) as my source as I too am exclusively streaming music and concur that it’s been able to handle all the different bit rates seamlessly from Qobuz and Apple Music. *It’s as seamless as switching between the apps on the iPad Pro.*
One thing to consider though, is with this setup the OP will be restricted to the USB cable length and from my reading, it’s recommended not to exceed *1.5m
@u2u2 - Would you mind sharing what USB cable you’re currently using? I’m looking at upgrading to a better quality USB cable from the generic one I’m using.
