Help with room treatments

I have alot of glass behind my speakers and also a TV between (see - beauty and the beasts under systems for pics), yet my system sounds great to me. The speakers are forward of the TV by at least 8 inches.
After hearing all the stuff here about room dynamics, today I placed very heavy blankets over the windows behind and also over the TV to see if acoustic absorption panels may give me better sound. I did not hear any differences on several of my favorite test cuts in near field listening.
Could it be that my SRS-SDA Polk speakers are better than most at eliminating the reflections given that they phase cancel signals coming from the left speaker to the right ear and vis versa for the left ear?
Or am I that untrained to hear differences. I think I have good ears, am a musician etc. Perhaps I picked up very subtle increase in the solidity of instrument placement. but that is all I heard.
Comments?

You do have a few things going for you that many do not, your room is large and your speakers are well away from the corners. As Rob mentioned...you are listening at a fairly close distance also. On top of that...your ceiling is a non-mirror of your floor.

Also, the Polks are somewhat laid-back in sound which has to be a plus with your many hard surfaces. The polk SDA technology does work very well in some system setups and my guess is that yours is one of them...the Bob Carver technology that I have built into my Sunfire Theatergrand (Holographic Image circut) can also work very well in some system setups...at least mine does with one pair of my speakers although it does not work well with my di-pole Apogees.

Large rooms with lots of setup flexibility along with seating flexibility require very little room treatments campared to smaller spaces that most have...see how lucky you are!
