Nice find well I know who won this battle...
You do ?
Only recently I remarked in another thread as regards these two arrangers how virtually all KORGS sound crappy out of the box and this is definitely as good as out the box and still imho it sounds better than the Yamaha. Yamaha again highlighting old stuff like the Shadows guitar sound ( already there in Tyros 2 etc.)
I will add some demo one day highlighting how the PA1000 can sound after decent tweaking.
A much more interesting point is this:
Apart from the gigging artists here like Don,Donny, Deane, Dave, etc. who set great store by only using one keyboard and preferably a lightweight one , any home user would imho benefit much more by a combination like the following two, which would be cheaper than one PA4X or one Genos, even without monitors.
Yamaha SX900 + Korg PA700
Korg PA1000 + Yamaha SX700
both sets would cost approx. 2900 euros in Europe, I would say :take your pick !!!
