Looking at new amp for Totem Mani-2 signature

I have a Musical Fidelity A5.5 integrated pushing my Mani-2 Sigs (250 watts/8 ohms, 400 watts/4 ohms and 75 Amps peak current.  I am wondering what if anything might be gained by going to a Conrad Johnson MF2500A t (250 watts/8 ohms, 450 watts/4 ohms and 35 amps peak current).  The mani is supposed to be current hungry and the published numbers on the A5.5 are  over twice that of the 2500A.  Anyone care to edumacate me?
