Thanks for all the responses to my OP, folks!
I have never had a problem getting height in my images, when the material calls for it.
Like in the track on Chesky's first "Ultimate Evaluation Disk", with the Mozart flute concerto, where, on all my previous systems, and my current one, the flute is always at the correct height for a person standing and playing the flute.
Like wise, on the title track of King Crimson's "Islands", there is a cornet that comes in at about 2:00 in, that is also at about 5.5 feet above the floor, just at the correct height.
I ordered Chesky's CD with the LEDR test on it, even though I know you can get it for free. I also want the rest of the material on the disk.
