I also have a Nexus 5 with a Dragonfly (Black), and I can use it with Spotify, but have to freeze UAPP first, otherwise when I plug in the Dragonfly it keeps wanting to open up UAPP. It's a minor hassle, but worth it for me sometimes.
1. Freeze UAPP in Titanium Backup, or some other way
2. Open Spotify and start playing through the phone's speaker
3. Plug in Dragonfly with headphones connected
In Settings/Developer options/Networking, make sure MTP is chosen under Select USB Configuration
This setup doesn't give bitperfect through the Dragonfly, but it will serve as dac/amp and sound better than through the headphone out port of the phone, especially with certain gear.
