The room and speaker position is critical and Soundstage can be vastly improved through 1) digital room correction (e.g., Dirac) and 2) going with active speakers (e.g., Linn)
Bookshelf speakers that renders 3D soundstage
Recently I am on a quest to find a pair of bookshelf speakers under $2k that will render 3D soundstage. The soundstage does not need to be much wider than the speakers that are approximately 7-8 ft apart but, within the soundstage, I am particularly looking for the decent depth, focus image and pinpoint instrument/vocal separation. The other sound trait I am particularly looking for is the nimble, agile bass that could go down to around 45 Hz -3dB. The pairing amplification is going to be Parasound A23. If you have experienced / auditioned that, please let me know.
