***Why not carefully listen to each unit a few times and then if you cannot discern a difference or make a decision, either buy the cheaper unit or then do your blinded testing? ***

Well, that was exactly my point in the first place. Going the scientific route is pretty pointless, I think, for something so elemental as home theatre, but you had previously asked me how I would propose to compare a 1066 vs a 950 in a blind situation, and I told you. I did not propose to make the test any more sophisticated than it deserves to be. You are absolutely right in that if you do only a few trials and can hear a difference, then the difference must be so gross that ANY comparasion (dare I say an ABX test...sorry...) would pick it up.
