This might work. You could get a Parks Puffin with the coax spdif option and then connect that to a streamer.
Integrating a wifi turntable into my existing Chromecast Audio system
Due to my home's construction I have an integrated amp with CCA in the optical port to cast my FLAC music collection from a NAS Drive. I want to add a turntable and add either a lossless or non-compressed signal from that turntable to the CCA. I am told Yamaha's
Vinyl 500 wifi turntables
and the MusicCast app of theirs won't work to get where I want to go. Any ideas how I might get a hi fidelity signal from a remote turntable to my CCA based system.
