Can't wait to hear your impressions when you get it all lashed up and running. I have M22ti's as mains and really like them. They are perfect for my medium/smallish room. I also have M3ti's in my computer room and I love Love LOVE those little things. I'm sure you'll be suprised by the performance of those minimonsters. I've never heard the EP500 but based on the reviews here it should serve you well. My 350 does just fine.
