As others have mentioned, I'd recommend the best BlueSound streamer that fits your budget.....Node nano, better yet Node, better yet Node Icon.
The BlueSound's software is brilliant, it is simple to set up and use, and will not be a limiting factor in your current set up. As you upgrade your system components, you can add a linear power supply for better sound, and later a dedicated DAC for even better.
I still use a BlueSound Node 130 with my high mid-fi system, albeit with a linear power supply and an excellent Denafrips Pontus II DAC......this combo has served me well over the last 4 years as I've upgraded all of my other components, though at this point will be upgraded.
