I am not sure if this is exactly what you are referring to but the NAD C 390DD has some form of digital EQ on board.

Direct Digital Amplifiers
I am very excited about the concept of direct digital amplifiers, such as the NAD M2 and the new NuForce DDA-100. There are others coming out too. I would think these amps are in their infancy. I would like to know if anyone has had direct experience with them and what are your impressions. I would like to see them accessible to digital equalization. Are there any models that incorporate this functionality?
