I may be wrong about Stern changing their mind on the number of LEs. I based that assumption on not seeing the LE numbers of KISS on their website. Having just looked for LE numbers of other recent machines, I don't see those numbers either. So it seems that this is not out of the ordinary.
I'm still surprised the KISS LEs are only 600. They could easily have sold 1000, based on the current rate of sales.
On audio, I reckon Stern should integrate wifi in their new system. Upgrades would be easier and sound possibilities awesome.
I just got Sonos Play 5 which sounds out of this world.
KISS or any pinball would sound incredible with a wireless setup around your mancave.
Stern have the capabilities with their new system. Gary, just do it and give our ears a treat!
It's not wifi, but you can add a cable to connect to your HiFi system. The KISS Game Features Matrix includes "New CPU mounted line-out audio connector for external amplification"
