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.

soix: re: my system-- thanks ! It's been a slow process, as my budget is modest by audiophile standards, but I enjoy my system as much as I enjoy friends' much more costly systems. For me, it's always been more about the music. I could live just fine without an audiophile system, but I doubt I'd survive for long without music ! 
@stuartk - take a look at KLE Innovations cables

All of their cables are very good and outperform most other brands and prices are in AUS $

I order from them direct and they take about a week to come from Aus...

If you want to try DIY here's a link to my own IC's that can be used for SPDIF...

Here is a nice BNC cable for $250 from the listings:

No connection to the seller and btw I concur with above the soundstage should change with each recording congrats on your new transport!
Another thing to consider for soundstage definition improvement is what sits under your components. Isoacoustic pucks are very reasonably priced & can greatly improve soundstage. Just food for thought... Also, I agree with uber that Nordost makes an awesome digital cable. 
williewonka, jond: thanks for the cable suggestions. Will check them out. 

boxer12: I haven't heard of Isoacoustic before. Presently, I've got the old style Stillpoints under the Heed. Will look into it.
