I just got the PinSound board from ArcadeShop this week and installed in my Royal Rumble today -- Wow! What an incredible boost in audio quality! Even just using the standard audio clips, it sounds like going from a crystal AM radio to a Bose Home Theater! I'm blown away by how amazing it sounds on the same exact speakers the factory board was using.

Haven't played many games on it yet, but so far I've not noticed any lag and actually it sounds like it's layering the various clips and music better than the original board (which would sometimes not play a voice sample if too many FX were happening on top of the music.)

Excited to start building custom sounds to replace the wrestler themes with their real music, and insert the classic Royal Rumble music in there!
