I don't have a real Adlib card but I have some SoundBlaster with same OPL2 chipset. I know that they are different in the analog path, an Adlib has a proper DAC reconstruction filter while most other cards and all emulations simply omit any filtering.
It appears fake86 adlib emulation (in sourceforge) has less features than x86emu (only registers sets 0x60, 0xA0, 0xB0 and 0xE0), not even 2-op FM.
DosBox is very accurate, it tries to calculate waveforms like the real chip does, instead of using floating point calculations, sin() functions and multiplications.
