In my opinion the ACDC Premium Vault is a little nicer than the the original. The game is essentially the same, but the lower play field window is much clearer in the Vaults than the originals. All the originals I've played the window looked a little foggy. Apparently this was due to the fact they clear coated over the window. The positive with this clear coat is that it could provide a little protection from small scratches (I'm assuming) that could occur on the lower play field window...mine hasn't shown any signs of scratches, but the jury is still out. The only other differences are the metal back box, latch system, graphics around the dmd display, smaller sub in the Vault (I added an external sub), and the lower play field design....the balance is pretty much the same....

mine does the same thing....

I think so, but haven't measured it....I always add an external sub to my music games. Prior to adding the sub the sound seemed fine...

I would add the Cliffy protectors....

yea the back box design is clever. I usually add Invisiglass to my games, which eliminates a lot of the glare, but tilting the dmd display helps significantly.

with the angled dmd and my invisiglass there's essentially no glare.....if you don't have the glass the bent plastics will help, but the angle on the dmd really helps reduce glare
