Well here is my final report on the Pinsound board.
It is a great product if what you are after is new cool music and callouts for your game. For this purpose the card is a beast and blows away the original sound card. And it has some cool features like a headphone jack and direct sub output. (But I already have Pinnovators hooked to my old board that already does all of that. At this point in time there are really no super cool download options for Whitewater though. One guy redid some of the callouts but the voice work is just not for me.
However, if you want original game rom sounds done perfectly like the original board does, you are pretty much out of luck.
I will admit that it comes close to doing this, and maybe going the extra mile by spending another $150 on upgraded speakers might help, but there is no way I can justify all the money the board and speakers cost to not be satisfied with the way my game is sounding right now.
And it is not just me, my entire family and everyone I have had stop by to listen, agrees that the original Williams sound board is faster and does not leave out any sounds like this board does. I forgot to mention that it sometimes just skips callouts or sounds whenever it feels like it. Arrrrgh.
I am even using a fast USB 3.0 thumb drive but since the wave files are not stored on the actual sound card, it just can't seem to always keep up.
So I will of course be listing my Pinsound+ for sale soon and I will nurse my existing sound card along for as long as it lives or until some company finally starts making replacement boards for these games.
