O/P.Depth & dimension are referred to as "imaging & sound staging".
The only speakers that I have ever heard personally that truly disappeared were Sonus Faber & Dynaudio HOWEVER both were driven by TUBE Integrated Amplifiers!IMHO you will never achieve truly holographic sound with solid state amplification.While good SS gear can render width & height almost as good as tubes were EVERY SS system I have ever heard fails miserably is in rendering DEPTH.
My reference for judging the ability of a system to render depth is Billy Holiday's Greatest Hits cd.There are 2 tracks that were recorded live in a Big Band Club.The recordings were mic'd in stereo from a distance of apx.20'-30'.When playing these tracks on my previous system(Cayin A-55T Tube Integrated Amplifier & Dynaudio Focus 140 speakers)the back wall of my listening room completely disappeared & you could literally see Miss Holiday 20' back,center stage!
Ask yourself how many of those guitar amps with a 3D like quality you are lookig for are Solid State & how many are Tube driven?I'ld be willing to bet most of them are tube amps.JMHO,good luck.
