I have had problems in the past with most ribbons as most designers don't marry them properly from what I've heard. The Legacy speakers (current) have done a pretty good job. I think I may be sensitive to coherency from top to bottom. I used to love the Apogees back in the day, but I thought they lost their magic when they were mated with their subs. I have never liked the ML speakers either. I do like Maggies, unless they are mated with subs. I'm not a sub guy for the most part. Bass is the most expensive part of the speaker. There are a few companies who make musical and coherent speakers that dip into the mid 30's or lower and they sound awesome.
There is a reason many choose a speaker for life if you would, but WHY?? What are you sensitive to? Do you care about a full range speaker? Can your room handle it? Staging, imaging, pace, rhythm???? Why are you keeping your speakers for life? Thanks.
