Not sure if I'm the only one on here using this card, at least it doesn't seem to get mentioned at all. I just recently bought it and will write a bit about it 😀
It's a PCI sound card from 2002 and sort of a successor to the EWS64 XL from Terratec. As such, it comes with a 5.25in I/O front module, which looks like this:

On the back of the card itself there are 3.5mm jacks for Line In, Front Out, Rear Out and Center/Subwoofer Out.
The card is based on the VIA Envy24 chip which offers 24 bit/96 kHz in/out as the name of the card suggests. A Sensaura mode can be switched on in the control panel, which is pretty similar to the gaming mode on Creative cards. It offers A3D 1.x and EAX 1/2 emulation. Going by a quick test I think this sounds reasonably close to a hardware solution, in fact UE1 games have the exact same nice pops that can be heard with a real A3D card 🤣 however, unlike with Creative, the caveat is that to enable this mode the PC needs to be restarted. Also, full HW acceleration is only to be turned on in the Windows audio settings if the card is set to Sensaura mode; without that it has to be on basic acceleration. So there is the question whether DirectSound is even accelerated in this case.
Sample rate can be customized from 8000 Hz to 96000 Hz or lock it to a fixed value. After installing the drivers the Windows click sounds etc sounded wrong until I set it to locked 96 kHz. Everything sounds fine to me that way, but I guess it does perform resampling on everything and when recording stuff it sounds logical that recording in the original sample rate would offer better sound quality. I'm not quite sure if this is related or comparable to Live!'s criticized DSP resampling issues. Also, on Sensaura mode it is forced to locked 48 kHz.
The greatest strength of this card is obviously the versatility provided by the front module to use it as sort of a mixer. To sketch the possibilites, I can hook up a Sound Canvas to the front line in (while using the built in MIDI ports, eliminating the need for a dedicated USB MIDI interface), Vortex2 to the digital optical in, EWS64 XL to the digital coaxial in, and finally the AWE64/SB16 from my second retro PC to the line in on the card itself; no need for annoying cable switching at all, everything is easily switchable in the control panel. The front module even offers a Wave Blaster header which not too many newer cards do, so there is the option of installing some daughterboard and driving it from a retro PC or using it from the main PC itself.
The catch is that the supported operating systems are limited to 98SE/ME/2000/XP. There are beta drivers available for Vista but as always with such products I really wouldn't give it the benefit of doubt, especially when installing them on 7. Quite likely this is the reason why those cards are available for very affordable prices in Europe 😀
