Replacing my Krell FPB 600 amp with a tube amp


Im thinking of replacing my Krell FPB 600 amp with  tube amp . I really love the power and bass slam of the Krell FPB 600.Could i possibly find that with a tube amp? I was thinking of the ARC Ref 250 mono blocks. I am also using an ARC Ref 6 preamp. The only thing i can think of with this much power and bass slam would be the ARC Ref 750se. Any other suggestions and how would the ARC Ref 250s as compared to the Krell FPB 600.

What specifically is it you are looking for in a tube amp that you feel the FPB 600 fails to provide?

Are there elements in the FPB 600‘s repertoire that tube amps fail to emulate that you would find difficult to live without? Ones you may have grown used to without realising?
