I've had my 3802 since xmas and have never even tried DTS Neo 6. I just always assumed that DPLII was the better choice. I remember everybody selling their 3801's and buying the 3802 just to get DPLII. I might have to play DTS Neo 6 tonight and see why everybody prefer's it. I have always loved how DPLII improved satellite. Even my wife's first reaction was that she noticed that the sound was no longer just coming from the center speaker. I use DPLII music mode for all satellite.
