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.

I will strongly recommend a fully upgraded GR RESEARCH XLS ENCORE. Less than 2k fully built is hard to beat for imaging, soundstage, depth and tonality. I have retailed so many high end brands and built diy kits including CSS. A fully upgraded XLS is hard to beat even for more than 2k. XLS provides well balanced sound leaning to neutral to warm, soundstage comes natural to these speakers.

I heard the Goldenear BRX at Axpona earlier this year. It sounded absolutely amazing and filled a largish room with sound. I think they were running on Parasound power too.
