I may add a good sound card to my standup cab though. I put a lot of time into the speaker layout and I'm not happy with the sound quality.
It just doesn't sound as open and dynamic as I think it should. The onboard audio has an option for 192kHz and it sounds sooooo much better then the default 44.1, but at that setting it doesn't allow you to use the EQ or any other tweaks.
That's actually sort of strange because I would guess that almost none of the content you would be listening to would have been recorded in that high of a sample rate to begin with. That means it's converting everything on the way out. Meaning if you took a 1 second piece of audio that had 44100 samples taken of it (original recording) and then decided to take those 44100 samples and represent them with 192000 samples there shouldn't be an audible improvement (not saying there isn't... Just that in theory there shouldn't be, in fact it should sound worse.) If they have an option for 48khz, 88.2khz or 96khz have you tried those? How do those compare to the 192kHz or 44.1khz?
Just for my own curiosity is all

Yeah, I can't imagine it would have been recorded at that high of a bitrate and also doubt the emulator is any higher than 44.1kHz.
I'll have to look into the emulator.
Anyway, 44.1 sounds condensed and devoid of any sparkle in the highs. Almost monotone. Kinda like a full range speaker that is muddy and can't resolve any detail in the highs. At this level, the software gives me an EQ which helps a little. I'm exaggerating a bit here for the sake of showing the differences. It's not
bad, it's just not the sound I want.
96khz is slightly better compared to 44.1 without the EQ. I lose the EQ at this level though, so it ends up not being much better compared to 44.1 with the EQ. I'd probably rank them about the same. They sound different, but neither one is much better than the other.
With 192kHz, the highs suddenly have the sparkle and clarity that was lacking in the other two settings. It sounds less muddy. The stereo separation also seems improved and it feels more like I'm standing in the sweet spot of a stereo setup rather than across from a monotone single speaker. It's not perfect and could use some equalization, but it's definitely clearer.
Could be that the audio software is introducing some other kind of processing at that level. I don't know.
Those are the only 3 options it gives me. I'll look into the emulator (Makaron).
