Pretty much every analog pre-amp will be worse than a digital version. What you want is a DAC that is also a pre-amp and does the cross-over fully in the digital domain. Its not an easy or cheap thing to do considering there are very few products on the market that are aimed at stereo setups with subwoofers.It seems like subwoofer considerations would be better handled a number of other ways post-DAC to allow for flexibility. An analog preamp, or by using subs that provide thru routing and incorporate their own analog or digital crossovers, or by using an audio interface and its matrix bussing features to send controllable and mixable outputs to one or more sub inputs.
If you want to do room correction you would also want to do that in the digital domain, and you could do that in front of the DAC. To correct multiple subwoofers you can also do it after the analog stage, because at those frequencies the extra distortion added by the dsp wont matter.
