Yes, I bought the Pa1000 mid 2019 as I do like Korg's OS having had Korg's before.I was wanting very much to like it but even after EQ adjustments into the night my ears kept saying no.
Individual voices were fine but combining with styles the overall sound was as if playing behind a thin blanket. (Even on Headphones)
Even now I'm puzzled. Fortunately my local dealer offered full refund so I purchased a very clean T5-76 which sounds excellent.
