Revel M20. You will not need a subwoofer. Very highly reviewed. You can get them used here on Agon for a fair price.
Many reviewers use this as their reference monitor.
Forgot to mention with the S25's you really want the stand4 to attach them. I would also fill the posts with sand to weigh them down.
You may want to consider the Totem Mani-2. With enough power driving it, it will fill your room with solid bass. No need for subwoofer.
Active Event Opal with built-in near 500wpc of total power each plus room correction pots beats with price and performance models priced 5x as much.
