I should edit my response above. The truby wort tasted different but not odd, some like the truby wort over the non-truby one.
You can read the experiment here, http://brulosophy.com/2014/06/02/the-great-trub-exbeeriment-results-are-in/
What kind of yeast you used? What is your fermentation temperature? Are you able to control your fermentation temperature?
There was an experiment done with dumping everything into the fermenter, and the product tasted the same like the trub separated one.
