Clearly, you may receive many different answers/opinions on what your problem may be. So my opinion will only be one of many!
While the Disc Doctor Miracle is supposed to be a top quality cleaning product, it is also, from what I understand, notorious for needing LOTS & LOTS of rinsing. I am only venturing a guess here that perhaps you did not rinse enough on that particular record and that residue from the Disc Doctor may be contributing to the sibilance you are hearing. If you did not have sibilance issues before, a re-clean of that record followed by heavy rinsing, perhaps 2 or 3 times with high purity water would be the first thing I would do to see if that solves the problem.
