Integrated for B&W 604 S3 in the 1000 to 2000 rang

First, I must state that my budget restricts me to being an audio-enthusiast (not phile). I have a pair of B&W DM604 S3 and am looking for an integrated amplifier to drive them in the 1000 to 2000 (new or used).

I listen manly to rock like radiohead, travis, David Gray, Dave Matthews and coldplay. However I also listen to a lot of acoustic like Chris Smither, Greg Brown, Dylan, Nanci Griffith, Joni Mitchell, and others. Occasionally I will listen to jazz/vocal like Miles Davis, Nina Simone, Herbie Hancock as well as others. Needless to say my musical taste are young and it seems rare that people review listening to components listening with this kind of music.

I am looking to build a budget system with my B&W and would like to begin with a nice solid state integrated in the 1 to 2 proce range. I have read many good reviews about the Simaudio, and have found lightly used ones in my price range.

Questions:
1. Could someone please suggest a good integrated for my speakers and my music type?
2. Is wattage an issue if I like to listen to music loud sometimes or would something like the simaudio be fine for creating musically accurate loud music?
3. Could I add a subwoofer (B&W ASW600) directly to this integrated or would I have to increase the amps?

I hope this does not make me sound like a head banger, but I sometimes get the feeling that most audio-philes listen jazz and classical and when things get crazy they take out their rolling stones. In the end I want a simple, quality system that delivers younger music accurately and some times loudly.

Thanks for the feed back
