Replaced CDP w/ Transport; Now, Soundstage Changes Dramatically w/each CD. Why?

Here's something I've never encountered. I've borrowed  a Heed DT Transport and am loving the increased resolution, compared to my Jolida JD100 cdp BUT, now the sound-stage expands and contracts, depending upon whichever CD is being played.The effect is very evident-- not subtle. This is really weird. 

System: Heed Transport -> Aqua La Voce II DAC -> Wells Majestic Integrated -> Silverline SR17.5 Monitors.
 
I don't even know where to begin. . . any suggestions? ? ? 

BTW, replacing the Blue Jeans BNC cable with an Empirical Audio BNC cable didn't change anything.

Quarter, dime, small ceramic tile, playing card, credit card, CD, industrial diamond, steel washer, aluminum washer. How will you know the CD is level whilst playing?

 If the component does not have threaded feet you will have to come up with a shim or two under one or two feet.


Here we see the difference between Audiogon's reigning theoretical physicist and an actual, you know, physicist. The actual physicist knows three points define a plane. Not one. Or even two. Three.

millercarbon, God gave animals and pianos four legs for a reason. He gave CD players four legs for the same reason. It’s so they won’t run around in circles.

What I think Geoff was referring to is that with 3 or 4 points the existing cdp sits upon you would ONLY need to shim 1 or 2 to change level.

Would be crazy to shim ALL existing points although you certainly COULD!

Actually my point was, for a component with a foot on all four corners, if you remove one foot the component could easily topple over. You can get away with three cones only if you can arrange them in an equilateral or isosceles triangle. Three points may define a plane but four points are usually more stable.
