I understand the speaker set up, placement and room treatment are important. I have been experimenting those in the past and was able to achieve / preserve resonably good SS with my current speakers when the recordings have those elements. However, recently I acquire a pair of Wharfedale Evo 4.2 and I found they could render much more SS depth and instrument separation than my current bookshelfs. I was able to hear the nuance I was not getting before.
The only two areas leaving room for my desire for the Evo are (1) more dynamics and (2) the lower end (54 Hz -3dB). I need to apply EQ and boost +4-5 dB in the 40-80 Hz for my satisfaction. I maintain 3 ft to both side and front walls to avoid early reflection. As such I do not wish to place the speakers any closer (which I have done) to acquire more room gain for the lower end. I like the Evo 3D SS presentation but wish it a more allrounder in term of frequency response in the low end. After the experience with Evo, I was convinced speaker itself could be capable of rendering 3D presentation beyond the room control factors. That is why I am asking the question.
