Firstly, I wouldn’t get caught up in comparing specs as that will likely lead to a bad decision. The MF and CJ are both more than adequate to drive your speakers, however will likely sound a little different. I am very puzzled by your comment as to what "so many people" are saying. Your amp got an excellent review in 6moons audio and having experience with 3 MF integrateds, one being the A5, I totally agree with the review. I hope these people aren’t dealers just trying to sell you something. What do you think needs improving? What are the deficiencies in the sound? If you do have some issues with your sound, I seriously doubt the amp is the problem, and you should look elsewhere.
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?
