$2500 in speaker Questions

I am looking to purchase a pair of sreakers for my new system. I am running Sunfire's Theater/Cinema Grand combonation. Now I know the three speakers I am requesting feedback about are very different but I'm looking for opinions of anyone that has had experience with more than one of the three comparitavely. My three choices are Martin Logan's SL3, Kef's Reference model 3, and PSB Stratus Gold. I love the sound of the Martin Logan's but the reports I have read complain about positioning and room shape and size. I heard the Kef's and fell in love but again my room is only about 12x15 w/ 10 ft ceilings. Where I can place the speaker is very limited because of where the door and Fireplace are situated. Someone recommended the PSB's to save some money. I haven't had a chance to listen to them yet. Are they comparable, or would the money I spent on the Sunfire equipment be wasted on them? Thanks in advance for your input.
