just pulled the trigger and bought it. Didnt read any bad reviews on it I like the features for pandora and internet radio. I'll only do 5.1 anyway the space in our house wont allow 7.1 or 7.2. i tried seting up the calibration side of things and it is way different from audessy doesn't let you change specific hz just small or larger I tried the setup mic twice. I have all polk speakers a cs2 center, 2 floor standers for fronts, 2 bookshelfs for rears, and a esw-v 10 energy sub. I definiely need help getting the best sound out of it any ideas or settings I can fix. Let me know all help would be apprieated.
