What's best bookshelf speaker for an 8x10 room?

I have a small 8x10 listening room. Looking for something used in a bookshelf. Currently have Kef 104/2's but they need more room to breath. I play rock/hard rock music. Been told Merlin TSM's and Kef LS50 are nice. Anything else you experts would suggest? Trying to stay under $1,500.
North Creek is another vendor, like Guru, who voices speakers to work close to boundaries, often a very useful attribute in small spaces. They are very good.
Echo North Creek kitty Kat Revelators. Always under the radar but superb speakers designed to play again back wall. Can't vault them. My best buy in speakers for a long time
