April Music makes a highly regarded preamp/DAC with multiple digital inputs. Tact makes a digital preamp with extensive room correction equalization. Grace makes a preamp/DAC that while targeted towards the pro market has the features you stated.
A combo preamp/DAC is an excellent idea that offers the possibility of very high performance with reduced clutter and significant costs savings when compared to more traditional setups. You might also want to consider several CD players that have digital inputs and could function as a preamp in a simple system. I know April Music and Quad produce such units.
