Your goal "to create a system that is very transparent with a lifelike 3D soundstage" is not likely to be realized with the Heresys. I am quite familiar with them, as my friend once had a nice pair of quicksilver 8417 monos driving his heresys, and it really wasn't anything special.
I'd go with a set of Quicksilver monos, audible illusions pre, and some more modern tube-friendly speakers like maybe coincident. Then I'd upgrade the source to the Sony SCD-1.
