It was also an spdif optical out which was super nice to hook into a better DAC.

Yes, although the actual streaming was lossily compressed, which more than negates any gains from using a better DAC.

(edit - this is incorrect; the Chromecast Audio was apparently updated at some point to support lossless streaming)

No, that is not true. Chromecast streaming is lossless, so it is certainly possible to stream hi-res flac files bit-perfect.

[JohnBooty]

Thanks for the correction. I think Chromecast Audio initially didn't support lossless streaming, but at some point it was updated to support it?

Regardless, thanks, and I updated my post!

Still using mine to this day

You can also put multiple chromecast audios in a group in google home and they will perfectly sync audio across multiple rooms like a ghetto Sonos setup!
