Best floorstander at $2k or less?

Currently have KEF Reference Model 2s as my mains and am wondering what else is out there in the $2k and under range new or used? They would be in a med/large room with good space on the sides and I could go about 1.5ft behind. Music tastes are varied, mostly chill/downtempo sort of stuff with a mix of other easy listening. My amp is a Parasound A23 Halo. I’ve got an HSU VTF-3 MK 2 subwoofer for mostly HT duty so I’d like to get something that I can match a center to as well as they will see some HT use at times (80/20 music/HT).

I’ve been keeping my eyes on the used market for speakers such as Legacy Classics/Sig IIIs, KEF Reference Model 3.2s even Polk Audio LSi15s. Any other good ones to keep an eye out for?

Thanks for any input.

 KEF R series.  I am very happy with the R700, you should be able them used in your price range.
Used Focal Aria 926 if you can find them.  I've heard a LOT in this price range and nothing touches them.
Vandersteen 2a sigs, or 3a sigs(used). The latter would have more bass, but both would be enhanced with subs.
Totem used?

Triton 5s are $2K new and Triton 7s are $1,400. I have the 7s. They are an excellent speaker for a wide range of music. Check out the reviews.
Second vote here for the Tritons. 

Thanks for the input,

I figured there are a bunch of choices and no definitive targets so I'm going to keep trolling the used market. I like my KEFs so I'm in no hurry.
