The best monitors for $1000 used

There must be many to choose from since technology keeps trickling down.
When I play my music at a reasonably loud level, everything in the room resonates. To keep this vibration from reaching my components and introducing noise I suspended the components. The place it makes the biggest difference is the turntable. But all components benefit from the isolation.
Regarding the speakers, I prevent my floor from resonating therefore the music is emanating from the speaker only and not from the floor as well.
Believe it or not it all made a huge difference. I highly recommend it, too bad I can't patent it but I didn't come up with it first.
Tyler Taylo Ref, JM Reynaud Twin Sig or Triangle Titus ES depending on what you are looking for and what kind of power amp you have. There are many others but if Quad 11 or 12 make it to the top list or ProAc 8 or 1SC, then my list holds strong.
