"Worth" is a personal judgement. I have tried both of these models in my local music store. The 2K definitely sounds and feels better to me when I play it. Worth the price difference depends a lot on how well you play and who you are playing for. As with all musical instruments, you get into diminishing returns as soon as you hit the middle price/quality range. There are a lot of other brands worth considering once you get into the 4 figure price range, of course. Are they worth the price? You have to decide for yourself.
