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.

The technical guys, Almarg, Eric and a few others are invaluable to this site. If you love these speakers as you say, the advice from these contributors can be helpful in keeping you from making a bad choice.
Had no idea the CAT amp had such a low impedance.
