I have Vandersteen 5A's (gorgeous Kowazinga finish) and are using Ayre electronics with them for a fabulous sound. I saw that you have Krell already, and I don't blame you for not wanting to replace them. Krells have always been a high end product, and I am absolutely sure they would work well with the 5A's. If you had the luxury of listening to some tube, some s/s, of the top 5 or 6 manufacturers, you would hear differences that would would only be "slight". Get the 5A's, set them up properly, and be happy.
