s2000 vision audio upgrade

[smileman83]

Hi guys- newbie again here. have been reading about the sound on the Vision series. also have seen/heard about the Multimedia sound upgrades, speakers upgrades, resistor additions, etc.
 My questions are in the Vision line, there are 2 0r 3 speakers? The sounds are the reel sounds and then of course when , in this case, the video game starts when you hit Slingo.

What are my upgrade options? Are all machines capable of introducing a MM board to change the sounds? How does it handle the video game sounds? are the larger dog ear speakers any better than the slimmer original ones?

Thanks everyone- I think I might be having fun soon!!
