best monitor available?

I am looking for some input on a potential upgrade to my totem mani2's. I only want to upgrade if it is an obvious improvement (therefore no mani 2 se) and I do not want to change my electronics. (EAD amp/pre pro with latest dacs.) All listening is nearfield, 20ft w by 12 ft deep b7 8 ft high exercise area with speakers on the wide wall 1 foot out. Listening to all but classical, with a velodyne sub for lf. Large amount of off center listening of music and open to small floorstanders if necessary. Have thought about revel gems, wilson benesch, jm lab, verity and others, but only have current experience with revel and totem. I am flexible on price. thanks for your input.
