usual speaker advice question

Listen room – finished basement game room 17ft by 30ft 7ft ceilings. Power : a four tube 6550 valve amp producing 50watts or a 200 watt high current Conrad johnson amp. My current speakers is a set of double stacked Klipsch kg4 on top of Klipsch fortes. Normal Listening levels for me is - 10 to 11 on the dial. Type of Music: rock, classic rock, blues. I like a large soundstage, nice mids and a touch of slamming base with clear top ends. Back end of game room is my workout space so usually I listen to music for a hour or so each night when I do my workouts.
I have a bit of the upgrade bug and looking to get new speakers. My current speakers move a lot of air no doubt and can sound fairly nice at times. However with some music the bass seems to get a bit muddled at time and the highs a bit bright.
My speaker budget is $1000 – on the used market that should get me speakers that cost 2000 to 2500 originally. Looking at Dynaudio focus 140, SCM 11, Totem model one sig, Monitor audio GS10, Proac 1s, etc. any thing else I should be looking at or any recommendations?
My problem is I can’t do listen tests where I live so it pretty much role the dice and buy something sight unheard so to speak and since it’s the used market would not be able to return so would have to be able to resell for same price.
