bits is bits


Being a retired IT tech, Iʻm a "bits is bits" guy. I keep seeing people rank different  streaming services against each other and I have to say, Iʻm mystified. Modern recordings are all digital masters and remastered. If two different hi-res streaming services, say Qobuz and Tidal, have the same track available, why would one sound different from the other, let alone better?

 

The stream is being fed over TCP/IP from the source, and I see no reason that it you were to do a cksum on the same file/track being delivered by either streaming service, that they would exactly match.  So why do people claim better sound from one streaming source over the other.  Iʻm assuming they are both full resolution sources, not mp3.

It’s one thing for the digital masters start out as the same ’bits’ upstream at the head end.  It’s another thing for how those ’bits’ are reproduced downstream at the playback end.  There’s theory.  And then there’s application.   Here are some discussions from the Audiogon archives.

@steakster You write:

"It’s another thing for how the ’bits’ are reproduced downstream at the playback end."

How is that different between streaming services?  I would think that both Tidal and Qobuz start out with the same digital data.  Then transmission of that data over TCP/IP should be 100% accurate.  Thatʻs the great blessing of computer technology.

So if your streamer receives exactly the same data from either service, then why would they sound different?  Why would one streaming service sound better than another, assuming they are both offering the same exact data file.

It seems that you’ve visited this topic before - link.    Apparently, you weren’t satisfied with those responses either.   Good luck in your quest.

Great question. I have no clue. Myself and many experienced audiophiles pretty much unanimously agree that Qobuz sounds best from listening comparisons. I switched from Tidal years ago. 

@steakster The earlier topic I was involved in had to do with the discussion of data transmission over USB cable.  

This question is really quite different.  Sorry my description didnʻt make sense to you.
