Not all Model 1 Genesis systems have great audio, not all Model 2 systems have horrible audio. I like when the techno nerds start blabbing about "for the best ____". When I play this stuff, I want it to look and sound the way it did when I was a kid playing it (which at the time of Sega was an RF hooked up to a mono 19 inch tv). I didn't know I was missing shit, because it was what it was and I loved it for what it was.
I wouldn't spend too much time or money worrying about Optimal Sound and Video. That's just me.
