A good solid state amp that is basically an arc welder will work fine with your speakers. however, you have exceeded your budget. Which is not a problem if you are not in a hurry. do one thing at a time. Don't rush. Mark Levinson 23, 23.5, 20.6, etc. Big Thresholds, Krells, will work fine. you just have to determine which amp's sound you like. Also, if your CD player has a volume control, you don't need a pre-amp at this time and can get one later and stay within your budget. Upgrades should always come one at a time. So, lets say your CD player has volume control, then you only need the amp as long as you like the DAC from your CD player, which in my opinion, typically are not very good because the power supplies are very bad in most CD players. As long as speaker placement isn't a problem, the room size of 12 x 12 isn't a deal breaker. Then, later get a decent DAC and use your CD player as a transport. That will make a huge difference in sound. "if" your CD transport is decent.
my opinion, small steps. one upgrade at a time. make friends with the sound of the equipment before upgrading.
