According to this comprehensive review, all 3 opamps are in the line out stage. Two for I/V and one for filtering/line driving : https://www.guru3d.com/review/asus-xonar-essence-stx-soundcard-review/page-8/
Btw., are the two big electrolyte electrolytic caps next to the RCA jacks coupling capacitors?
I did not find anything about is, yet.
Thanks,

I have an original STX in an Ubuntu 24.04 PC. Since upgrade to 24.04, I notice that the capture volume only operates on one side, so the other is fixed at 0dB.
Thanks!
I actually had everything I needed already in my workshop.
So while I upgraded the card from Burson V6 to V7 (the Wima caps were already in), I replaced these with 220µF Nichicon ES, parallel with 1µF Jantzen Z-Cap and two 47nF Styroflex (I wanted to use 100nF but did not had them in stock) each.
That one of the caps is bent is on purpose so the card still fits with my network card next to it.
It sounds amazing!

just wondering is there any way to like connect this sound card over usb? are there not any pcie to usbc adaptors?
There are many, you can find them easy.
Do you want to use 7.1?
Otherwise I would suggest a regular USB DAC.

Then a enclousure for a graphics card should be the way for you.
They have space for more than just one slot, so you can fit also the extension card for 7.1.
If you can connect it depends on your PC/Notebook.

I have been wondering about something like this but never tested it.

That would just work if it is the old PCI card and has a desktop PC to connect.
If he uses the PCIe one and just has a notebook, he needs to look for a thunderbold PCIe dock.
Maybe there is something cheap to be found on Aliexpress bit on Amazon it would be one of the external graphics card boxes for 300$+

only ask as something in my pc is emitting emi and card is picking it. its fine when i put it in some else's pc . ideal world would be some thing with a small foot print or something i could 3d print a case for
If you have something emitting, you should try to do something against the emitting.
For exaple desable WiFi (in the UEFI) or Similar.
Adding an EMI shield or moving the card to another slot or position (with a riser connector) would be also a good try.

Hey people,
what do you think about building a daughterboard for ST, STX,D2X for balanced out? Maybe with relays to switch unbalanced/balanced amd back.

Honestly these days just get an external USB DAC from SMSL or Topping and it will likely have much higher real-world SINAD than an internal card can achieve. Unless you need more channels than stereo.
I need 7 channels 😉 (and i can not see how people get along with 2 channels and passive crossovers).
And no, even if i could get along with a pure stereo dac, i wouldn't buy a already built device. I like it, when i can take influence on the devices i use, and make it as i need it.
Best regards

It has been quite a few years I moved from PCI soundcard to usb DAC mostly because there was not enough room to apply any more modifications to Xonar STX. By the time I quit it was looking like this
A second PCB is attached underneath like a double slot PCI card, holding dedicated regulators for each chip on the soundcard involving cutting copper traces and the alike. I also converted the output to balanced passive I/V. I cut the RC filters on the opamps feedback network, and wired mini XLR. The I/V resistors were soldered on opamp sockets and allowed to test different values from as low as 2 ohm up to 100, 22 ohm being a nice compromise.

Ah ok. You might want to see if you can find an Essence STX II 7.1 with the daughtercard. It doesn't offer balanced outputs but it does have separate RCA outputs for all 8 channels which is quite a big improvement over 3.5mm stereo jacks. I went from the D2X to that and it was a pretty big improvement.
I used REW to do room correction with Equalizer APO.
