Apples and oranges: my choice is Krell but in your system you may prefer the Bel.
I am not convinced passive pre is the way go with either however. The Krell will benefit from a quality active pre, especially a KCT via CAST. Otherwise you will not get all the performance possible out of the 400cx. I must reveal that my set up is a KCT CAST connected into a 400cx so I am biased IMO.
