So, I think mine finally bit the dust. Should I be able to take over the cover and look for bad capacitors, or anything else?

For a Little Dot +1, not worth it.So, it looks as though a Windows 10 update broke the original driver. I installed Unified drivers and all is right again.
Quick question:
Would I benefit from using the rca outs from the card into a little dot +1 amp?
For a Little Dot +1, not worth it.
The STX can not send it's Dolby headphone out the line-output jacks (RCA).
If you use lower Ohm (Impedance) headphone, like under 50-Ohm, then a Schiit Magni or JDS Atom might be worth it.
The STX headphone jack has a 10-Ohm output impedance, so it can cause lower Ohm headphones to get a bloated bass (louder, less detailed) bass.
I've plugged 32-Ohm headphones into my STX's headphone, which was not really a big issue, but I think my O2 head amp helped bring out the detail.
I used AD757BR op-amps, but there are lots of other good op-amps.Thanks Purple Angel,
So, let me ask another question. Using the ST (my version is pci) primarily with 600-Ohm DT990's, what would be some good op-amp upgrades here in 2020?
Thanks in advance
Hello alphanumerics1, one question if you allow me, wima capacitors have a way to be assembled? I can't figure out if they have a positive and negative pole and how to differentiate them. Thank you.Sure, let me give it a shot.
Here's the stock board with the cover off,
The three socketed 8 pin op amps for the I-V stage and output stage are visible top left. Zooming in,
The I-V stage is to the right, two JRC2114D shown. The output differential-single converter / low pass filter is the LM4562 at left. It has four 2n7 (2700pF) caps around it, the small white rectangles right next to the op amp marked 2n7J400. Those caps are not bypass caps, but rather the low pass filter. The circuit is almost certainly based on the one in the PCM1792A datasheet,
So, apart from removing the stock op amps and replacing them with NE5532A (mouser part number 595-NE5532AP) I desoldered the four caps and replaced them with WIMA FKP (mouser part number FKP2D012701D00HA00).
Which OP AMP config be best if i want best possible surround, wide sound-stage, lossless details, neutral and clear output.
I have come across multiple quotes in this thread and other related treads saying that one op-amp made the sound stage wider and improved surround over the other. Some even claim it to make difference to level of improving surround by clearly distinguishing and giving clear separation to channels over headphone making movie watching experience improved a lot.IMHO, I doubt surround sound and sound stage are affected by which op-amps you use.
@18000rpm The BURSON® V5i is the largest dual-amplifier module that will fit under the ASUS® XONAR® Essence™ ST/X/II's stock RFI shield; I have it shortlisted for the I-V of my STX with a Signetics® NE5532 shortlisted for the line-level buffer. In either of my µATX desktops (viz., the ASUS® CM1630-06 (ASUS M4A78LT-M/CM1630/DP_MB) and/or the Hot Rod gPC (GIGABYTE® GA-MA78GM-S2HP 2.0), I'd need the original ST to utilize any of the V5, V6 Classic, or V6 Vivid, short of retrofitting any of Burson's 5-1/4" half-height head-amp modules; both desktops' 'boards have the PCI x1 and x16 adjacent, with the legacy PCI 2.2 slots at the system unit foot in both cases.
