The only Sony "uber-" SACD player I heard was WAY too long ago: SCD-1 (at a dealer); and that was enough. Sony knew how to design around its format, and you literally had to drag me out of the listening room. The sound was so good for DSD I forgot which speakers they were playing through as well.
I'd figure the later iterations of Sony's flagship SACDs would be just as good; my only concern would be the age. If you've got a local, good audio shop close by that knows Sony - that would melt away some of my reticence.
