if I were you I'd get used to the new pre's sound, then, once you've got a sense of its personality, ask yourself if you want a more 'romantic' (maybe tube), 'gutsy', 'analytical', etc. DAC. in some ways, DACs are like cables: the audiophile's way of achieving tone controls (since our pre-amps don't have 'em). changing two important parts of a system in close succession is, IMHO, not a good idea.
