I would consider the Node 2i.
The ChromeCast Audio is good, however no every app streams to it bit-perfect, so I can’t say the apps you would use would sound as good as the Node 2i or similar. However, for $40, it’s an amazing product, just a shame that the Implementation is not uniform, casting from your Chrome browsed on a computer for instance is not bit-perfect, yet casting from Room or an app like Android Hi-Fi Cast is.
