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.

macdude: All I can say is that the sonic profile of the Heed and Moon transports (with the same cabling) was very different. I suspect a "better" bnc would not have made the Heed more appealing to me-- its designers would appear to prioritize resolution above all else. I've heard DACs like that, too and they're most definitely not my cup of tea. This is not to say that my system couldn't benefit from a different bnc. 

There are some gear that imply very 'bright' sound that increases the resulition artificially ,  causing small details to jump to the front of the soundstage and giving illusion of increasing resolution but it's not, it's harm the natural and neutral of the sound ,it's making the highs sound bright,the mid fatiguing and lost of low/bass and dynamics .
