Bookshelf speakers that renders 3D soundstage

Focal's original Mini and Micro Utopia are still stunning

IMHO, this is correct @lucky_doggg7 . I heard the Micro Utopia BE in a friend's well thought-out system and it was stunning in it's presentation of a fully fleshed-out soundstage. In his room, it was one of the best soundstage presentations, both side to side, and front to back, that I've ever heard.

Thank you, @lucky_doggg7 @reubent, for bringing Focal (JMLab) Mini / Micro Utopia to my attention.  I do not mind going up scale to standmount speaker like Mini Utopia at all as long as they fit the bill.  The transmission line design of Falcon IMF-100 as suggested by @donvito seems also promising too.  Interestingly, I was looking at another similar design speaker PMC Twenty5 22i the other day,.  The new one is over my budget but a used one might come up.  I also came across Bryston Mini T standmount speakers yesterday.  Anyone had experience with it?

Ditto - Fritz Loudspeakers could suit. Well built, good bass extension, reasonably priced, very spacious.

I also like the BBC heritage loudspeakers, especially those from Graham Audio. Derek Hughes is a very accomplished designer/engineer.

I have had really good luck with Totem Dreamcatcher speakers.  They are favorably reviewed and a mini marvel.  Slightly larger but still punching well above their price point are the original Andrew Jones Pioneers. Both of these can be found used in great condition at modest prices. 

If you can find a pair of LSA 1s they will make you very happy. Properly set up they will deliver just what you are looking for - at a bargain price. Look for reviews on-line. The original LSA 1s sold for $1100/pair but occasionally come up for sale here on Audigon for less than half of that. Totem Dreamcatchers are also a good choice.
