Point of higher priced streamer?


Hello,
Assuming I have separate DAC, and I just want to play songs from iPad by Airplay feature.
In this case, I need a streamer to receive music from my iPad -> DAC.

What’s the point of high price streamer? I’m bit surprised that some streamers are very high priced.
From my understanding, there should be no sound quality difference.
(Streaming reliability and build quality, I can see it but I do not see advantages in terms of sound quality.)

Am I missing something? If so, please share some wisdom.

@jaulbrich The streamer is just conveying the digital content. A CD transport can vary based on its ability to correctly read a CD and manage errors. The streamer is just taking the ones and zeros from the source (e.g. Tidal) and passing those data, verbatim one hopes, to the DAC. Are there errors to make up for? I don’t know, but I should hope there would be error correction that doesn’t rely on the streamer. This is computer data. Qualitative changes can happen in the DAC, sure. But not before, I’d think. But maybe I misunderstand how this works?
Of the eight or nine streamers I have auditioned in my own system, I hear the biggest SQ differences between streamers whose manufacturers take power management and design seriously and those who do not. Additionally, vibration damping and build quality of digital outputs appear to have some impact on the SQ I have heard. That said, I’ve never found the SQ differences between competently constructed and designed streamers and DACs to be nearly as dramatic and obvious as, say, phono cartridges or even between high quality versus poorly made vinyl record pressings. But I’ve only heard a small portion of the devices available for purchase.  That said, any product that reduces “digital listening fatigue” is something I’m willing to pony up a bit of cash for...within the limits of my budget and priorities. Suffice it to say, getting the entire digital recording and playback chain “right” is no walk in the park. My hat is off to any designer or company that manages to make digitally reproduced music more faithfully resemble the original sound that was recorded.
I should add that one way that I am thinking of improving my streaming quality, now that I have the room tamed, is using Fibre Optical cable. One way that streaming can degrade in quality is when analog noise goes from Ethernet to the DAC. My microRendu should have this issue, though I don't know if that is the case since I have not compared anything "better". My understanding is that Fibre Optical cable (I do not mean  Toslink) cannot carry analog noise from the 1's and 0's being transferred on the Ethernet wire.

The cleanest solution to this that I know is the Lumin X1 DAC which has a Fibre Optical input. You get a network switch like this,

and connect a Fibre Optical cable ($50) between the 2. Likely the best streaming quality you can achieve. Unfortunately the Lumin X1 is $15K. However, if what I am saying is not BS (I have not tested this myself yet)  then I expect more DAC manufacturers to have this as an input. If they can have I2S as an input why not Fibre.

I emailed Alvin of Vinshine (Denafrips) about this (and other topics) and he said they were aware of Fibre's benefits but it is not the highest priority at the moment.
Do you really take your hat off for this? I suspect the sound you are attempting to achieve is nothing like what was originally played. Vinyl most definitely is not "true to the source". Boring, technically accurate, digital is. You may not like it, but it is.

For a DAC manufacturer to add a fully isolated data interface to carry audio, let's say 32/784 to cover all possible cases, we are talking <$10 in volume, perhaps $25-50 for a low volume manufacturer and I am being pretty generous.

Your analysis of fiber optic is correct, but keep in mind Ethernet already is galvanically isolated though there is a path for high frequency noise.
