If you do upgrade, you might want to consider a tube amp, especially with the Focals. If I were in your position, I would look into the Rogue Stereo 90 which you can get used for about $1,200. The Rogue is a great sounding amp and is built like a tank, also has excellent customer service.
If you could up the ante a bit, I would consider a Conrad Johnson MV60.
