Best setup with Chromecast Audio


I am having trouble getting aptx working on my mobile devices – and with that not fully working, am also trying/experimenting with the Chromecast Audio for wireless(ish) streaming. The device has two outputs - optical/toslink and stereo/analog.

The optical requires a toslink to digital coax adapter (which I have an okay one). Not sure if it is degrading the audio, but assuming that it isn’t, would putting this through the Sprout have great results (especially with lossless style files)? I am using the cast directly for some tunes.

Alternatively, I could use the stereo out to the analog in on the sprout. However, this uses the chromecast audio’s DAC instead of the sprouts. I am of the impression that the sprouts is much better.

Any advice?
