    My Sony ES supposedly has the ability to create virtual speakers that makes you feel that you really have rear or side speakers, even though you really don't. Does anyone have experience with this on Sony or any other HT, and how well does this really work? How can I test this to see for myself how well this works?

    Geoffry,

    Yes it does work. The phenominon is called psycoacoustics.

    A 2 channel source that goes through the processor and the

    sound that it output is specialy processed so that the timing

    coupled with reflected sounds makes your ears and your brain

    think that there are rear speakers. Tonight for the first

    time I used this feature on my Onkyo 787 and I have to say

    I am impressed. You can close your eyes and pinpoint rear

    sounds that flat out "shouldn't" be there.. Infact I checked

    the surrounds 3 times to make sure they wern't playing!

    I wouldn't use this for movies though, why bother when you

    have DD,DTS,DPL.. But for 2 channel music it is a neat feature IMHO.

    Some recordings have the psychoacoustic effects built-in!
    Examples:
    Beatles - I am the Walrus (in the latter half of the song)
    Jimi Hendrix - House Burnin' Down (near the end)
    They both used stereo phasing [​IMG]
