I finally took the time this evening and put one of my spare TILT!Audio boards into my msf game. Took only a few minutes to replace and it plays very nice.
My msf has a few more mods like extra leds in backbox speakers, big color pin2dmd and also the whole gi is rgb. But to be honest the biggest thrill is always the new sound. Of course I replaced the speakers as well to get more volume and clearer sound.
