Speaker suggestion:
Try a used pair of Spendor 1/2 classic monitors. They are legendary for doing exactley what you listed. Play all kinds of music, good bass, efficient, musical, etc, etc. In your price range and tons of information/reviews on them. Check them out.
There are not many listed on Agon right now, but wait for a newer pair with a nice finish - they are listed all the time. I am going to buy a pair for my 2nd system after I sell some stuff. $1500 will get you that plus the stands.
