Hi Jacky, i'm a happy owner of the QA 2010i. I do not find the 2010i too harsh.
A couple things to try
1. Do you have tone controles on your amp. Is the treble perhaps set too high?
2. i dont know if you have put bungs in the back ports, remove the bungs on the back and hear what happens.
3. what also can help is to experiment with positioning the speakers closer of further away form the back.
Hope this can help.
