The real question is which S.S. amp has the correct soundstage? Some depth and dimension are artifacts that exist in part to the fact that your speakers are set out in your room and also from the room itself. Many recordings with depth actually shouldnt have depth or at least have less depth than is presented. At least this has been my experience.
The most important factor in soundstage imaging
Everybody wants a system that images well. There are many discussions here positing equipment changes that will improve imaging. Some people think the magic wand is cables, others are sure it’s the preamp, and the ones that don’t think it’s preamps, think it’s amplifiers. And, of course, speakers are (correctly) mentioned.
However, the single most important factor in audio stereo imaging, is increasing direct radiation and decreasing reflected radiation, by moving the speakers away from the back wall, and away from the side walls.
