That would certainly explain why QSound is so good (at least to my ears).

Not that I'm doubting you or anything, I know you are a regular fountain of knowledge, but can you show me a spec somewhere that shows stereo JAMMA?
The closest thing I've ever seen is the Neo-Geo flavor of JAMMA which *does* support stereo.
Ken Layton:
Jamma audio standards:
If mono cabinet, pin "L" is speaker -, Pin "10" is speaker +
If stereo cabinet, Pin "L" is left speaker -, Pin "10" is left speaker +, Pin "M" is right speaker -, Pin "11" is right speaker +
These standards are listed on the A.M.O.A. website (www.amoa.com) but their site is currently down.
