Doesn't that reduce sound quality by going from analog to digital and back to digital again?
I have to say using bluetooth with these speakers is not the best way to take advantage of their sound quality.
I use Roon with iTunes, Tidal, and Flac files to directly play to the Kef's. Sounds great and I get a very nice interface. That won't help with Spotify though and I agree the app is still pretty bad. It was unusable for months after the speakers came out.
according to their specs, the sample rate of the USB in is 2x higher than the optical, which is why i started by connecting my laptop via USB for music. That, plus the AppleTV 4 doesn’t have optical out, I haven’t bothered to use the optical. i know that i get a good phantom center from the RCA. I can’t say how well optical works.
i could use the usb out when watching from my laptop, but i’m usually using the AppleTV, so i just run it all through the same cables for ease of use. i stopped using a wired connection for music, again for convenience. i’m not a bluetooth fan, but it’s nice to be playing music wirelessly. i move around, and take the music source with me so i can change the playlist or volume.
incidentally, i use bluetooth with the muo for the opposite reason. i started with a wired connection, but use bluetooth more now so i can leave my phone connected to a charger, and carry the speaker around with me.
