If you have had the Mirage's for along time and this has not been bothering you, then you have to look elsewhere...
First, I have no idea how old you are, but it isn't abnormal that as we age, Our high frequency rolls off and we become more sensitive to peaks in the 3k to 8k range.
I disagree with the thought of too much in the chain, unless, ONE of those items is causing the problem. What has changed in your system. Have you always had a problem with peaks or has it come with a few changes? Time to borrow or exchange borrow with a friend and try to find out where the culprit is and it could certainly still be your speakers, IF you have recently added the complete digital front end as a source and have just never heard real detail from your speakers, so if thats the case, it could be your speakers.... Hopefully this isn't confusing....
