To update, I feel the speakers may be just about there as I have not noticed any glaring differences in their sound lately. I have again made some changes placement wise. I found 2 positions that seem agreeable to my ear. One has slightly better bass, the other a slightly deeper sound stage. I have all the measurements written down so now I’ll go back and forth between the 2 and see which I prefer the most.
I am still considering a cable upgrade at some point. As an example I have been told that AQ Robin Hood have a good bass reponse, the William Tell even better, so if I go that way I'm thinking I can use the speaker position that gives a better soundstage and the cable upgrade may produce the bass that the second placement did so best of both worlds? Then again, it may lead to have to totally change speaker positions dependent on cable response. What a hobby!
