Here's an interesting podcast on Scientific American:
Can better than CD quality music be streamed?
What would be needed to make that happen with our current technology/equipment now?
How should the music be mastered? SACD?, 24bit/96KHz (or higher) WAV?, other options?
Possible equipment setup
If I want to use headphones in this scenario I would imagine using a DAC like a Chord Mojo and a decent pair of earphones/headphones (Shure SE846)
Sonos equipment setup
I have a pair of Play:5 set up in stereo and I stream FLAC from Deezer Elite - sounds pretty much like a CD to me. Interestingly, according to this, Sonos supports audio files up to 16 bit and 44.1 kHz: https://sonos.custhelp.com/app/answers/detail/a_id/80/kw/16bit/related/1
Just curious: Sonos, is that a software or hardware limit (or both)?
