Hello, I was wondering if anyone has had any experience in setting up a Chromecast Audio with their Hi-Fi system via the digital out and noticed a drop in sound quality? Spotify (320KB) on a Windows 10 PC PC connected to Chord Mojo DAC connect via USB Chord Mojo DAC connected to Denon amp via RCA interconnects Denon amp connected to Tannoy speakers The sound on this configuration sounds good. I thought I might improve the sound by using Tidal CD quality streams to a Chromecast. I came up with this method instead of running the Tidal application the Windows PC as I can't control the Tidal app on the PC via my mobile like I can with the Spotify app using Spotify Connect (the PC is a headless unit). With this in mind I did this: Samsung Galaxy S6 running Tidal Chromecast connected to Chord Mojo DAC via optical cable Chord Mojo DAC connected to Denon amp via RCA interconnects Denon amp connected to Tannoy speakers ...but for some reason the sound quality sounds flat and I can't understand why? It's defiantly a downgrade in performance compared to the Spotify setup which I didn't anticipate considering the lower bit rate and the same DAC is doing the processing. Some things I have done. Checked Tidal is running at Hi-Fi quality Checked the Chromecast if running in 'Full Dynamic Range' I have noticed that even when running via the optical out on the Chromecast the Google home application allows you to change the treble/bass as well as the volume level on the unit which make me think that the Chromecast is manipulating the digital signal presented to it from Tidal. Seems odd that the digital out would affect the sound quality in a detrimental way? Does anyone have any advice to offer? Maybe I should wait for Spotify to come up with it's CD quality service instead ?
