I just went through this and got a Pro-ject Stream Box S2 Ultra. It definitely sounded better than my iPhone. Other potential improvements that I've found to have good ROI in terms of improving sound quality of my Pro-ject streamer are:
1. Turning off WiFi and using an Ethernet cable
2. Getting a better quality Ethernet cable (Supra Cat 8 has worked well for me and was a notable improvement over an AmazonBasics Cat 6 cable)
3. Getting the right USB cable. The Phasure Lush is working really well in my system.
