You are not being singled out sir, error corrections involves all things digital, including streaming services. There are many reports that different routers have different sound performances and with some to even have higher floor noises than others
People using ROON also are plagued with similar problems....and also ethernet cables as well as the Hosting servers...etc..
But dont worry, just dont get there and dont look for it

No one saying buying more expensive card is going to eliminate that. There are just differences between cards. Most obvious are between 2 categories: Consumers or Industrials, and coincidentally, industrials are more expensive due to better reliabilities.
Among industrials, 3 that stand out the most is Edge, Micron, Swissbit. With Edge being the most musical, Micron being more neutral...ect...
But if you cant tell the differences, why bother ? Why even debate anyways ? Be happy and stay with the cheapest cards. No one will criticize you at all.
But if you want to know how it is possible that MicroSD can effect performances, people are posting up scientific evidences just for that. Ultimately, you do whatever you want and fit your needs.
All of this reminds me a saying between car enthusiasts. Why bother with more expensive cars ? They just get you point A to point B, and I am happy with my PriusSpeed Limit is still the same regardless
Also it's not totally necessary to invest into expensive Industrial microsd to get great sound. There are commercial cards that performs really well too. I have browsed through the various audiophile forums(including chinese ones), and this is my list of commercial cards that has been recommended by others on the net:
Sandisk Extreme Pro
Sandisk High Endurance
Sandisk Max Endurance
Samsung Pro Ultimate
Kioxia Exceria High Endurance
Kioxia Exceria Plus(Pink Color)
Just to note:
1) Transfer speed isn't the ultimate determining factor on where a microsd card sound great or not. There are slow cards that sound great
2) Industrial cards are never ever marketed as intended for audiophile purposes. It was discovered by audiophile enthusiasts that these industrial cards not only are more reliable, but they also provided really good sound quality.
3) In fact these Industrial cards lacks the SLC cache that some Pro-consumer grade cards have(which boosts read/write performance). Industrial cards are firmware tuned for better error correction thus they write much slower.
4) Take for example, This Swissbit S55-U industrial card has insane manufacturer rated TBW(Terabytes Written).
Manufacturer Rated TBW for 128GB microsd cards(do take note that the MB/sec varies across vendors, but all based on sequential writes):
Sandisk High Endurance 117 TBW
Sandisk Max Endurance 702 TBW
Samsung Pro Endurance (2018) 512.4 TBW
Samsung Pro Endurance (2022) 819.9 TBW
Lexar High-Endurance 135 TBW
Kingston High-Endurance 117 TBW
ADATA High Endurance 234 TBW
Transcend High Endurance 350V 351 TBW
Kioxia Exceria High Endurance 189 TBW
Swissbit S55U 940 TBW
Micron I400 175 TBW
WD Industrial XI 384 TBW
Integral High Endurance 366 TBW
WD Purple 64 TBW
ADTEC Industrial(MLC) 313.6 TBW

Hence I said different cards will have different performances. It just happens to be the most obvious between consumer grade VS industrial grade.
but i am so done with this topic, I will let people who decide to do so, do so. Because I am sure that whatever the debates are, I will always rate both EDGE=MICRON with different signatures and will always be my primary choices

Most people have the assumption that digital is fault free and cannot have errors. They take the example of storing a text file and retrieving it without any errors as example of how digital cannot go wrong. But when we talk about the context of digital audio reproduction, it is time sensitive streaming of millions of bits which does impose its own set of limitations and faults into the system. I think this video explains very well what are the issues with digital audio, specifically with the reproduction of high precision accurate audio:

Isn't the read speed quite slow compared to Sandisk 2TB Pro though?

Read and write speed are not the factors of the music performances. But you are right, Sandisk Extreme Pro is a lot faster.

100Mbytes per second is more than enough for DSD512 playback. But of course nobody is against having a faster performing card.
What’s more important I feel is the long term reliability and sound quality performance aspect of the microsd for our usage case of DAP storage.
From my understanding, some of these Kioxia cards are made in Japan.

So Bloom Audio couldn't find anything wrong with my DX340 after I sent it in, they couldn't reproduce the intermittent lingering hissing that I heard when quickly changing tracks. Maybe the problem has fixed itself or it will eventually hiss again a few days after I get the DX340 back, I just reflashed the latest firmware again before I sent it in.
Hopefully the upcomming firmware can fix the issues, I will also try reflashing the stock firmware too.
