Sorry to say I cannot give you an answer because I have not heard any of your particular pieces of equipment, although they all seem very nice. I am however familiar with Mcintosh amps. I can only relate to my experience with my own equipment. I think that I was able to "clean up / reveal those little hidden jewels within a recording / sound track" each time I moved up the lines with different speakers first and then tried different amps to see how they affected the speakers. Also, it would probably help more to match all three front speakers and then work on the amplification. Hope this helps!
