I'd second the recommendation of the Peachtree Decco. I'm using one as a preamp and DAC with a tube power amp in the winter and as a stand-alone integrated in the couple of summer months when the class A tube amp puts out too much heat in an un-airconditioned house.
The versatility of the multiple inputs for the DAC, including USB, make it a good candidate for a later office system, as well.
