Office streaming solution?

Currently, in my office, I’m using my iphone to stream via a 8 year old Apple Airport connected, to a DAC, and then to an amp. While this setup has worked reasonably well, the Airport is old and no longer working seamlessly with the latest phone software. E.g. my phone has trouble finding the airport on the network, and it requires multiple restarts of Airport and phone to get them to work together.

I’m looking for a more stable and decent sounding solution.

Options:
- Use Audioengine’s B1 Bluetooth to input to my amp
- Bluesound node
- Other ideas???

Thanks for your suggestions.
