Another “which studio monitor should I buy thread”! Woooooottttt!!!

Also, I did use the search function, some useful info, but I have a very specific question, so I wanted to get a little more clairification. I A/B’ed some monitors at Guitar Center, and really liked the Adam A7X’s, and also the DynAudio BM series. I am especially looking for a 7” – 8” driver per speaker and no sub. I have a home office and an untreated room, and these monitors would be ONLY for listening to myself play the Kronos, and I would do NO recording at all, therefore these speakers don’t have to translate well to anything, and must be capable of being a bit adjustable in an untreated 12’x12’ office.
Now, my question is this: is there a set of monitors that can be purchased new in the range of $400 - $500 / speaker? I would probably be looking at the used market, and would like to pay around $250 - $400 / speaker (which I figure should be doable from new speakers around 4-500), but there seems to be a gap in selection in the $400 - $500 range, with things like the HS80M and KRK Rokit’s in the $300ish range, and then a jump to the $600-$700 / speaker range for the A7x’s and the BM 6A’s. What speakers am I missing in my target price range?
Thanks in advance!
