@cleeds Quite possibly but if ethernet protocols didn’t sort this then the internet wouldn’t work. Error checking and correction are built in. The streamer input side deals with this so the output side doesn’t have to.
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?
thx

@grislybutter Cool, glad to help. The signal coming out of the streamer containing 1s and 0s does incorporate a timing element. Jitter is therefore a “thing” from the streamer onwards in a way it isn’t up to that point. |
@steakster I’m really not sure that’s “as I wish”; I’m a listening first guy who then seeks to understand the physics/science which might explain what I’m hearing but the SR stuff is from a different planet. What the heck are “contouring” and “tuning” actually supposed to be doing to a digital signal? Modifying the 1s and 0s which amounts to corrupting the data? Changing the timing? Or modifying the way in which RFI noise accompanying the digital signal is handled? This sounds like leading edge witchcraft… |
Many aspects of music perception are not measurable. But when it comes to altering electrical properties in any way, there should be something the designer used to decide how to alter the electrons that is subject to measurements. If claims are made based on electrical engineering, the engineer should be able to describe the electrical changes and why it improves sound quality, even in a theoretical way. I can decide for myself, by listening, whether I like the change but I don't accept that something meaningful is happening without a reasonable scientific explanation. I believe in the mysteries of music perception but not electrical magic. Give me some kind of science. |
@8th-note I am with you buddy. A decent streamer (say, $2-3K) is fine, after all, that is what decent custom PC costs - nice box. no fans, screen - it all costs company to make. $20K? No, thanks. |
