I need help trying to decide which bookshelf speakers to purchase


Let me try to narrow it down.
I have an NAD T777 V3 with surround sound.  I am looking for two bookshelf speakers for stereo listening.  I want to keep the budget around $3K new or used.  Room size is 20' X 18' with an additional open foyer with a stair well and an opening to a hall way.  Not a totally closed square room.

So far I have tried the following speakers.  Elac UB5s, SVS Ultras, Revel Concerta 2 M16, Paradigm Prestige 15, and Dynaudio X18.  We don't have many audio stores around, so I can't listen to many speakers.  We have the Best Buys. and NFM, but not much else.  So far I have purchased all speakers without hearing them except the SVS Ultras.

I don't want to keep spending money on speakers without hearing them.  My plan is to get some recommendations on speakers, and travel to places that have new speakers so I can listen, or take a chance on used speakers without hearing them.

Let me list the speakers I have tried.  I would rate the speakers I have tried in this order (Favorite to least favorite)

Dynaudio X18,
Paradigm Prestige 15 (a close second),
SVS Ultras,
Elac UB5,
Revel M16

I noticed some speakers for sale on this site.

Totem Mani 2 Signatures,
T+A Elektroakustic TCD410,
Dynaudio Contour 20 Bookshelf Speakers


I know it's a stretch, but based on what I like in speakers so far, do you think I would like the ones I listed? What are their characteristics?
Thanks!

If you don't have anything constructive to say - move along.  Yeah - I'm talking to you bongofury!
You need easy to drive speakers so Nola Boxer 3s for under $3000, great reviews of them all over the internet.
KEF LS50 are nice passive for very clear audio. I own the KEF LS50 Wireless (active), and I am a big fan of how they don’t get in the way of my vinyl collection. Apparently, in 2016-2017 they win a number of awards. Also, outstanding options for digital streaming, which I’m not heavily into other than Tidal or Spotify occasionally. The DSP of the LS50w is nice if you actually have to put them on a bookshelf or console as they have an associated App to control it based on your listening room. $2000 is a solid buy for these actives, and probably half that for the passives.
musicloversaudio, we do have Paradigm in town (KC) and I listened to them (Prestige 75F) and they sounded pretty good.  I agree they take up the same space when you consider a stand with a bookshelf on top of it.  I must be old school.  I like the bookshelf look.
