The Pro-Ject Pre Box S2 Digital is a great suggestion. It's excellent as both a DAC and digital preamp. To better this unit with a stand-alone preamp is not exactly cheap. I added an AVA Fet Valve CFR preamp between the Pro-Ject and amp. It improved the overall sound but for many, I think the margin wouldn't justify the cost.
The Pro-Ject is one the best bargains currently available in digital audio. Dan Wright of Modwright Instruments was very impressed by it:
