Need help with the chain


Noob question
I'm looking to use my iPhone as a source for Apple Music to play hi-res tracks.
I currently have two speakers (duh), an Odyssey Kismet in a Stratos case, and an Integra DTR 40.3 AVR. The iPhone is connected to a Lightning to USB 3 adapter, which then has a Dragonfly with a Big Sur (3.5 to RCA) connected to an analog channel on the AVR.
I want to get rid of the Integra but am not sure what to replace it with. As in what kind of component do I need? I just want to be able to plug my phone in and go.

First, be aware the iPhone limits its digital output to 24/96, which is still pretty good but you won’t get 24/192 if that matters.  Second, ditch Apple Music and get Qobuz.  Lastly, you should look at a good stereo integrated amp to replace the AVR, and if you share your budget and what sound characteristics are most important to you you’ll get some good recommendations here.  Hope this helps, and best of luck.
