Used Floor Standers for around $1k

I'm setting up a new system and hoping to get some insight. The room is approx 30' x 15' with a vaulted ceiling, though the sitting portion of the room where most music listening will occur is probably a little over half of that. I have a limited budget.

looking for advice on used floor standers in the $1k ball park from this website. hoping to avoid a subwoofer. I don't have much time or ability to listen to examples in person. I'm fairly new to the high (mid) level audio equipment game. We will play it loud from time to time but I don't think that should be primary focus. So far, I've seen Monitor RX8, Tannoy Saturn S10 and Revel Concerta F-12's on here that look interesting. and from what I've read, the Goldenear Tritons are impressive, but probably out of my price range.

for amplification, i'm planning on a NAD D7050. I've been impressed with NAD and want DAC included and like the airplay option. I also have an unused NAD 2400 amp I can hook up if need more power, or I can swap in Peachtree 125 from another smaller room (which means I would need to find a replacement for that). want to keep things on the simpler side if possible.

Any thoughts or advice is appreciated. Thanks
