Heh... I was the one who started the whole discussion on the LS-212 compared to the YMF262. And you beat me to make note of the real YMF262 instead of the LS-212 clone on the 82C929A Retro games 100 showed.
But really, I don't know if the clarity of the LS-212 is better due to a superior DAC to the YAC512, but it sounds noticeably clearer than a real YMF262. I would assume, too, that it has weaker sound output than a real YMF262 because the audio amp on every 82C929A is the same and the sound is noticeably more distorted on a real YMF262 than on the LS-212 when the volume of the FM Synthesis is maxed out. Have a listen at what X-Wing sounds like on my 82C929A: http://www.youtube.com/watch?v=2F2uU3K0Ps0
The FM Synthesis is not as clear and comes out much rougher than with the LS-212, but since the distortion is more uniform on the YMF262(if that makes any sense) than on the LS-212, it doesn't sound as bad.
@Retro games 100: That 82C929A is actually the same as the one I have with 2 differences:
1) It's on a different-colored PCB(mine is on a pale orange PCB)
2) There's an Analog Devices chip instead of a Crystal chip
Wonder if that 82C929A will output the same sound with X-Wing as my 82C929A.
You gotta love OPTi's sound hardware(well, anything older than the 82C931, where a really lousy YMF262 clone was used, and since there is just one chip on an 82C931, you can't improve the FM Synthesis). If you find an 82C929A or 82C930(seems like a condensed 82C929A from what I've seen), you've got yourself quite possibly one of the best SoundBlaster Pro clones you can get(my main problem with it is the Stereo is reversed). For me, nothing beats the 82C929A as a SoundBlaster Pro clone. The ESS AudioDrive comes close, but due to one note being off in the ESFM YMF262 clone, I have to rank it below the 82C929A.
