McIntosh vs. Marantz ...... sonics?

I have a few 22xx Marantz receivers (2226b and 2250b) which I really enjoy. They sound sweet.
I have heard so many good things about McIntosh that I am intruiged, and maybe interested in trying a Mac. I am thinking of an int-amp or receiver.

Would I really hear an improvement or is it mostly reputation?
I am considering trying it but Mac gear is so much pricier than what I have.

Thanks,
Rob
