I've heard great things about IIX and I want to try it except that I probably won't be in the market for another 3-5 years. I won't be uprgading until I'm done with school (2 yrs hopefully) and or some new technology (ie. something that outdoes DD or DTS) comes out that is a must have. Plus, I have to upgrade my center, surrounds and CD player (I love the thing but it only has a limited life line left) first.
