I can't give you any info regarding KPS 20i , but have owned KAV300 cd for about 6 months and absolutely love it. I definitely feel it to be a significant improvement over KAV250. Also for what it is worth, I spoke to a customer service rep at krell when making my own decision and he spoke very favorably about the KAV300 despite fact that it has been discontinued. Good luck.
