The extremes that I have heard are as follows: 
Vertical imaging goes up through the ceiling in my listening room and into
the attic about 3 feet. My ceiling is a typcial flat 8 foot ceiling. This 
occurs on the Chesky Jazz Sampler and Test CD using the UP track.
Depth imaging goes back 30 feet or more on many of my classical recordings.
The speakers are placed 3 feet from the back wall.
Lateral imaging goes out past the outside edges of my speakers by 7 or 8 feet
on a few CDs. My speakers are placed 2.5 feet from the sidewalls of the room.
Good recordings for this are "Yellowstone" by Mannheim Steamroller track 3 
(listen to where the birds are located), the venerable Dark Side of the Moon
by Pink Floyd (standard CD, not even the audiophile versions are required) 
tracks 2 and 3 especially the clock chimes, the footsteps and the laughing
voices. 

In talking to Martin Logan about this, I found out that this is better than
average imaging, probably due to the decent listening room size, shape and
acoustics that I have. Believe me, it adds a great deal to the listening 
enjoyment of my system.
