By nature, a pre-amp would generally not include a digital input. Typically a pre-amp is an analog device and a digital input would indicate that you need a DAC inside the pre-amp.
There are some all digital preamps that have digital inputs, but convert the analog sources to digital before "processing" them. There are also several pre-amp/DAC combinations on the market.
I've used the Monarchy Model 33 DAC/pre-amp and thought it was excellent at the $400 used price I paid for it.
You will increase your choices if you simply buy the pre-amp you want and buy a an external DAC to provide the digital input you require. The output of the DAC would be connected to your analog pre-amp, therefore the "pre-amp" would not need a digital input.
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.
