The difference between Qoboz stream vs purchased songs

@tomrk  Here's a nugget for you:

” See an example of that in the attached graph from my Roon core playing 96/24 from Qobuz as a track ends and the next starts: a steady send rate to the playing endpoint, and a big burst receiving the next track. It’s all on 1Gb wired local network to the router, so that 140 Mbps burst is no problem.”

Also from the article "I compared latency streaming 320 kbps as an even benchmark across services. Loading a new track in Qobuz takes on average 1,25 to 1,5 seconds. " Which is more than enough to download a 320 kbps MP3.

what do you think is more likely, 1) Your experiment is flawed 2) Qobuz is lying. The answer is obvious.

Logical fallacy: excluded middle/false choice.

Please feel free to conduct your own experiments. I’ve now done three, with three different streamers, with similar results. The experiment is so simple, it’s a bit of a puzzle as to why you resist, other than it allows you to keep the "argument" alive.

Of course, you’re also free to copy/paste here, rely on press releases and the like. Suit yourself.

@fredrik222  Yeah, that's why I showed the math.  I surprised myself when I realized that you could literally download a high-definition FLAC from Qobuz in just a few seconds easily.

I use Spotify most of the time since I drive a lot and like to listen to headphones during the day.  However, I use Qobuz when I'm listening on my NAD M33 which has the BluOS built in.  I stream from both my internal network and Quobuz, and you really can't tell the difference between the two in terms of latency or the quality.

And the difference between digital and analog is while you can still argue about the quality of the sound between components (speakers, DAC's etc), digital data in terms of content and timing of data packets can be measured and quantified in a way that gives you something that is directly comparable.

@cleeds  it just proves my point. You can do 30 experiments, or 300, and it will still only prove the point that you don't know what you are doing, nor do you know anything about the technology. 

So that's the end of the road. 

@fredrik222 Interesting thread  It appears Quobuz is using a either a network  protocol or an application technique that will try to dump as much data down initially (which probably works really well for short pop & jazz songs) allowing an instant start of the song and then giving a slower network the time to download the rest while playing the beginning of the song.

For most pop songs, it's seems like that initial chunk may contain the entire song.

It would be interesting to see what happens if he tried to play a long song to see if the data rate stays high even after playing the song starts.
