Driving Maggie 1.6s?

I would like to stay at $2000 or less, but would like to stay cheap and used until I decide what I really like.

I want to add 3D, air, and reduce the edge. Maybe you can suggest a tube preamp to get there. I primarily listen to vocals, jazz, and rock and roll.

I forgot to add the current system.
