I have no specific listening experience relevant to your question, but my instinct would be to go with a recent high quality, well reviewed, cd player with built-in volume control.
Why add the complexity, cabling, etc., of a full-fledged preamp when all you need is a volume control?
And I think that the usual audiophile instinct that separates tend to be better than combo units is not necessarily applicable in the case of a cd transport and dac. Transmitting the digital signal cleanly and jitter-free between transport and dac is a considerable technical challenge, with lots of opportunity for performance degradation if the design of either unit or the cable in between is not done to perfection.
