So, if anyone wonders what the sound difference is, I made a comparison that combines OPL and PCM audio so one can clearly hear the balance and filtering between these cards.
Edit: All tracks are downloadable so you can properly compare them in your favorite player.
I recommend listening with a good pair of headphones.
I should add that SB1.5 and SB2.0 are VERY sensitive to CPU speed and many games break the OPL2/Adlib music in a Pentium.
That includes popular games like Doom, Prince of Persia 1/2, Mortal Kombat 2, DOTT, etc..
I had to underclock the Pentium 200 (non-MMX) CPU to 90MHz (60MHz FSB), which at that point the YM3812 (OPL2) started to behave properly in games like PoP1/2 and DOTT.
BUT, at 60MHz FSB the SB1.5 CT1320C goes into buffer overflow at some point and stop playing auto-initialized DMA sounds altogether in games like Doom, this does not happen at 66MHz FSB.
50MHz FSB breaks SB1.5 and SB2.0 DSP completely and no sound can be heard after a second or so...
So not only speed sensitive games have problems detecting the SB cards at "higher" clocks, but the DSP of the SB1.5 and SB2.0 in itself is sensitive to clock, which is a completely different issue than the YM3812 (OPL2) sensitivity to clock.
So in general;
SB1.0 - SB2.0 should live in a 486, nothing above that.
SBPro2 and SB16 are much better paired with a Pentium.
EDIT: important links to shorten my signature.
