Replacement for Vandersteen 2ce

You can pick up the Vandersteen 3A used for very little money and it would be a big step up. 

(((((replacement speakers for my Older Vandersteen 2ce speakers. )))Before you jump ship.
It sounds like you could have an improper tilt back
in your set up to be complaining of that area amongst other things. Glad to see you are enjoying your new table
 Shoot me a call at Audio Connection NJ 973*239*1799 and Ill dial you in. Best, JohnnyR

Though I know it may not be something you want to hear...
My thoughts would go to changing first the speaker cable to AQ. A set of GO-4 isn't too expensive. I use them for my Treo's and find them a good match. Johnny probably knows your current cables and can give you good advice.
Second, I would change the Krell to an Ayre or Belles. They just seem to work better with Vandy's.
You have a nice system, but sometimes it takes a bit of tinkering to get 'synergy'. I think you chose a very good speaker, too.
Get Johnny's take on this. He is one of the best out there and won't try to sell you anything. Trust me.
