Everytime I notice that the wayback machine is slow, I curse about my german provider, enable a US westcoast VPN and suddenly it's super fast.
So maybe all these people complaining have crappy ISPs? 😅

CP2101N USB-UART in the middle, the USB hub might be a CH334P.

... and then a USB hub IC, a SOT-23-5 voltage regulator and ... another USB jack?
Framework module with a "hidden" RF IC for Zigbee/Threat/Bluetooth/etc. would be my guess.

oh damn, yeah, that fits much better than my guess :)

ohh! wait, that BGA IC could be one of the Intel Thunderbolt (something like the JHL854O) chips.

Solarpanele können (vorsichtig) auch mit Strom versorgt werden und ein bisschen heizen. Frage mich gerade, ob man damit mal die unterste Schneeschicht antauen (und damit alles zum Abrutschen bringen) könnte -- um dann wieder Strom zu erzeugen.

In my experience, G.fast and MoCA are both much more reliable and lower latency than VDSL2 (even with good equipment), so I'd strongly prefer the first two.
You can also go full bullshit and just run WiFi, like I did years ago: kittenlabs.de/blog/2018/10... (but maybe better don't) :)

If you want to do a "good enough" solution, you can also buy the super cheap 75Ω unbal -> 100Ω balanced balun adapters for CCTV/TVI.
There is also G.fast, which might be a _much_ better option for your requirements? Several vendors already offer G.fast modems for this configuration with an F conn.

Not a problem whatsoever, will work fine.
You can also just skip the balun altogether, the impedance mismatch and the unbalanced/balanced difference is not irrelevant, but VDSL2 needs to work over much, much, _much_ worse lines :)

SATA SSDs can't just map DRAM from the host like modern NVMe SSDs will do, so when buying SATA SSDs (for performance-relevant tasks), it's pretty important to make sure that they have on-board DRAM (which will make them more expensive).
This might also be related here?

This sounds like a bigger problem, like overheating controller (or just bad flash/controller).
I can (and have) filled up modern QLC Samsung SSDs (dram-less) from start to finish and while they'll drop down to something like 300MByte/s write speeds -- well, it's still 300 MByte/s.

"this isn't just magic EQ going on" -- might be, though?
EQ curves for human hearing/psychoacoustics are extremely loudness dependent -> en.wikipedia.org/wiki/Equal-l...
Maybe the new amp silently corrects for that? Many Bluetooth speakers do this for example.
