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.

dweller.... That is correct... I will tell you that this ARC Ref 6 is so awesome in sound that it will very likely be my very last preamp. You must hear it to believe and appreciate it. 
@tattooedtrackman - I believe your ARC is AWSOME! I've had many ARC components over the years and I put them on a pedestal. Can honestly say that my current system meets ALL of my needs. The only way I'd enjoy it more is A. A bigger room (e.g. 25 X 50 feet)  and/or B. Legalized THC. Long live music!

REALLY!!!!!!

Haven’t read any of the other posts, all I can say is "YOU"LL BE BACK".
The better I made all my tube amps sound with mods/circuit changes, the closer they got to the best solid state.
The only one that was close/equal to the best solid state was the OTL tubes, but you have to be careful what speakers you drive with them, which are usually the ones I don’t use.
