    I know I'm a Boring Old Fart, but I never /got/ "streaming."

    It's just playing music/video from the internet or another computer, Which has actually been fairly easy every since, on the 8th day, god created the LAN.

    I stream from my NAS to Pi2AES, nothing else required.

    Edit: oh yeah, Wi-Fi router

    @Cspirou Hm, do you have actual numbers/a study? Yes, comparing a CD player to a streaming setup with a Roon server, the CD player obviously wins. OTOH, streaming directly to a receiver with a Class D amp probably uses less power than using a CD player and a Class A amp.

    Streaming doesn’t really add much to a single setup. It’s the sheer mass that creates those huge numbers, and the fact that the simplicity makes people use it much more often than they would use a CD player.

    @zottel - I’m specifically talking about streaming services like Spotify or Apple Music, not LAN. I’ll dig a bit more but I saw a graphic that said watching 1hr on Netflix on your smartphone produces as much CO2 as charging the same phone 12 times. A local download would use far less

    It encompasses the whole infrastructure; servers, routers, computers, data collecting, etc. Things that are never involved if you play vinyl

    My problem with all that information is that it always talks about the complete power consumption including the devices used to display the videos. If anybody has numbers about the consumption of the streaming part alone, I’d be very interested.

    Leaving carbon footprint out of this and taking the conversation to pure sound quality, in my house CDs just sound better than streaming. Making streaming meet or exceed CD quality is likely more money and nervosa than I'm willing to deal with.

    Found it at last: In the website linked above, the graphs can be opened and then also downloaded as CSV. Their estimate is that 1h of HD video streaming (my guess: Full HD?) causes 6 Wh of attributable power consumption for data centres (sounds like too much to me, but ok) and 18.2 Wh for data transfer. So streaming HD video uses roughly 25 W of power for streaming alone, including the household network devices.

    So, transferring to music, @Cspirou your claim of loading a smaller phone battery of a bit less than (due to charging losses) 2 Wh 12 times actually fit if we’re streaming 192/24 content.
    I’d guess a CD player probably has a power consumption somewhere between 10 W and 20 W and thus uses some 20-50% less power. Comparing to CD quality streaming, not 192/24, it might be roughly equivalent (wild guess).

    @gixxerwimp According to a post about Synology NASs, the system itself requires roughly 20 W to run + 2.5 W per SSD or 5 W per HDD. So, taking into account that it won’t run only while you are listening, it uses quite a bit more power than streaming, which makes sense, too, as this infrastructure isn’t shared with others.
    My setup with a Roon core, a NAS, and streaming on top is the worst of all. :o)
