Quoted from dannunz:
I also like that I can get a head phone jack rt off the sound board because no one else offers a head phone jack yet.
Is the sound really improved that much?
My Data East Star Trek at pintastic had it installed. It had music and callouts from the original show installed. It was hard to hear it well in the free play area. I have the head phone kit but didn't install it before pintastic.
I think there was a noticeable improvement in sound quality just using the stock sounds. If you get your replacement music and sounds form a high quality source it will sound even better.
An added bonus is that if you get the pinsound board you can buy a flipper fidelity pinsound speaker set for about $50 less than their normal speaker upgrade kit. Since the volume adjust and crossover stuff is on the board then can sell the upgrade kit without those parts and make it cheaper. So if you factor in the head phone capability and the cheaper speaker upgrade path it makes the board price a little easier to swallow. Also don't forget that their board price includes free shipping.
After spending some time with it, I would definitely recommend buying one especially if you are putting it into a music pin like GNR.
