What is your budget?

If the above is your whole system, no other sources, I would replace the preamp and dac with a Directstream Jr. It would replace both of those components.

Or if you are mostly happy with the sound, start working on cleaning up your power, a regenerater or power conditioner, it all depends on budget.
