I have a pair of Unos and do not experience any brightness or glare, I would not trade for wilsons as your speakers when set up properly are state of the art and outperform any Wilson.Make sure that your room is properly treated, this is very important, do not use any silver speaker cables or jumpers as they are bright on Avantgardes. I use Mit Bi-wire, low going to the bass, high to the midrange, with a Mit Magnum jumper from midrange to tweeter. Get the best Mit cables you can afford.Use an Set amp, I use an Art Audio Diavolo, and your system should sing.Remember that the problems you are experiencing are system related, not the speakers. When everything is set up right the speakers are unbelievable.
