why expensive streamers


@soix and others

I am unclear about the effect on sound of streamers (prior to getting to the dac). Audio (even hi-res) has so little information content relative to the mega and giga bit communication and processing speeds (bandwidth, BW) and cheap buffering supported by modern electronics that it seems that any relatively cheap piece of electronics would never lose an audio bit. 

Here is why. Because of the huge amount of BW relative to the BW needs of audio, you can send the same audio chunk 100 times and use a bit checking algorithm (they call this "check sum") to make sure just one of these sets is correct. With this approach you would be assured that the correct bits would be transfered. This high accuracy rate would mean perfect audio bit transfer. 

What am I missing? Why are people spending 1000's on streamers?

This whole thread reminds me of the debate about amplification.  There are audiophiles that claim that if 2 amps measure the same then there is no sonic difference between them.

  I’ve tried several streamers in the $500-$4500 range and there are definitely differences. 

I don't claim to be the world's most sophisticated person (let alone audiophile) when it comes to digital audio and playing music from a cloud-based music service, or a hard drive/server.  I do know more than the average person about audio playback systems, acoustics and reverberation time, amplification, cabling etc.
What I have experienced firsthand is the sonic improvements that I have heard when moving source from a high-quality compact disc player, incorporating an outboard DAC (the initial offerings from Theta Digital, Wadia, etc.) and then moving onto a compute solution with an outboard compute-based DAC system. 
First a small Benchmark and then to a Lampizator Baltic 3.  Then USB from compute to the USB input of the Lampizator.  And the differences there were not subtle. 
Then along came a Lumin U2 and WOW! 
Can I technically explain why it sounds so much better?  Maybe a little.
But you know what else adds to the overall sound quality of these more expensive products?  It's still a lot of good quality and attentive detailed engineering.  These things still plug into a wall, have a power supply, have circuitry that are sensitive to resonance and heat, etc.  And there is still that pride of ownership.  Being able to look at something and appreciate what went into designing it, the build quality, chassis finish, the tubes that glow (in some cases) are also all parts of why we purchase what we do.
If that didn't exist then Rolex, Breitling, Phlip Patek etc. wouldn't be providing their watches in the marketplace.  I mean, don't all watches just tell time?  Why own an expensive one?
Same goes for cars; yeah, you can buy a car based on specifications alone, but specifications don't tell you what the leather smells like, how the door shuts so quietly, and how the engine sounds when you turn it on and how fun it feels when you take a corner at 70 miles per hour while still feeling so safe.  (These are just analogies so don't critique my driving habits, please!)
I know I am not helping the discussion specifically, just something I wanted to throw in there!
          

Streamers and dacs work in tandem. I wouldn't get the best out of a DCS Vivaldi DAC  using a Bluesound Node, just as I wouldn't get the best out of a Grimm using a Topping DAC.

Right the specs can only tell so much.  You have to test drive the car to know how it drives.

 

Far too much sense being talked here: I think I need to find a thread with a bit more nonsense!

Some great posts.
