Yours is a very open question, so it is a bit difficult to address it.
First of all, if you tell us a bit more about how do you like your sound, it would help us if we are to suggest you brand/models (bright, relaxed, detailed, euphonic,...).
You didn't say if you want to keep your current Sunfire amp or would like to change it as well.
May be you could start buying a preamp and listening to the results with your current amp and speakers and then decide the way to proceed. Do not forget the importance of cables. With so detailed speakers you'll notice them in the final result.
In order to conect an ipod, you could go with a preamp that has an integrated craddle for it, go for an independent craddle or simply connect the ipod to the preamp via a cable (jack to RCA).
To break the fire, I can suggest you a cheap, very good sounding preamp, that is hassle free. It is a Promitheus TVC passive pre. Google a bit to see what people think about it.
