It's funny, after all this extensive re-calibrating, I'm not impressed with the results. I have only lived with it for three days but plan on returning to the 950's test tone for calibration. Why? The scene in TWISTER where the boat flies at you and then over your head now sound like the boat flies at your and disappears over your head. The rain in JURASSIC park no longer sounds like it is falling on top of the Jeep, (with the previous settings you could almost smell the wet canvas). And in LOR I no longer feel like I am surrounded in the woods. The meter may tell me all channels are set equally using the test dvd, but the actual result is poor. But, this is the fun of having so much flexibility, you can tweak to your heart's desire.
