WSS works on purely 8bit bus so having only 8bit slot doesn't preclude it.

Which means the table in this post is wrong about WSS support, at least for those cards with no 16-bit sampling.
Bit of a necro-bump here.
I already had a much-loved NXPro and last week found a Basic 16 (MMSN810) for a nice price. Based on SaxxonPike's page and Rabanic's table I assumed it to be basically the same card with the only addition being a wavetable header of dubious utility due to it not supporting MPU-401. I certainly got that, but the differences were bigger. For starters where the NXPro has a volume knob and three 3.5mm connectors the Basic16 has no knob and four 3.5mm. Also my NXPro has a genuine YMF262 and the Basic16 has an "LS-212". But what really caught my attention was the DAC. The NXPro just has a simple Yamaha YAC512, but the Basic16 has a CS4248-KL codec, complete with two oscillators (16.9344 and 24.576).
Suddenly something clicked: I enjoy the WSS sound of my various Aztech 3rd gen cards but had not been able to get it working on the NXPro. I'd assumed driver issues or resource conflicts, but it looks more fundamental: no codec, no WSS - which shouldn't be a surprise as that's the situation with the - better documented - GUS vs GUS Max as well.
So I think the WSS support column in the table needs to be set to "No" for all the 1st gen cards without codec.
On the topic of 16b WSS, I don't think the table is wrong, it just needs qualification. WSS playback in DOS definitely has 16b resolution (just listen to it in Descent, it's as good as SB16 and vastly better than SBPro), but the table specifically mentions sampling i.e. recording. Can't confirm or deny that, but it sounds plausible enough.
