At 82 yrs old, 50% of the preset styles are not my generation. But I have two CD's with 3500 styles from all boards including the 7000 to use. The built in speakers are not to my liking but at less the $1500.00, I had room to add externals (Z5500).
I would call the PSR S900 the nearest replacement for KN 8000 at less than half the price.
