DAC vs. Preamp

I have just purchased Parasound JC1 Monos and will be getting Triton Ones soon. I will be using an Arcam cd player and Macbook Pro. I think I'm done with vinyl. Too much work. Would a good DAC be sufficient in this configuration or is a preamp still the way to go. I don't want the DAC to be a weak link yet money is definitely a concern. This is a brand-new system so I'm wide open to suggestions. Help,please.
