OK, after years of eyeing those Japanese sitdown cabs I'm finally getting one. It's A Super Neo 29 Candy. Will also be my first real JAMMA cab. This is the one:

I've also ordered an ArcadeVGA and J-Pac.
So I should be all set. Mostly.
My question is about sound. I have the option of having them (them being the now-famous Tao bros. at ArcadeInfinity) leave it in standard JAMMA mode (mono) or wiring it for NeoGeo MVS stereo.
Obviously I'm really using it for my PC though, and from what I've read NeoGeo MVS stereo wiring is a bit odd. So what should I do about sound? Any recommendations? Naturally I really want stereo output from the PC, but I'm not sure what to ask for or what I might need to do on my own. This cabinet is in great condition so I'd like to use the built-in components, don't wanna add in some crappy PC speakers or such.

Also - if it's possible, I would like to be able to use the cabinet for real JAMMA PCB's too.
Thanks.
Also, if candy cab owners have any other advice or remarks about using such cabs please feel free to share!
