I was contemplating upgrading my 3560 set but wanted to get some input before doing so. I am running 100 watts RMS and and have a sub so my components don't have to pull low end duty. Given that set up, which of these three components will have the best mid range sound? I am concerned that upgrading to the MM6 would improve my low end (which I don't need) at the expense of mid range SQ. Thanks for any input you may have.
