I tink that would be a great combination. I Originally had the rotel RCD-1071 connected to a Bel Canto DAC and was very pleased with the results. The benchmark DAC has received great reviews, so your really cant go wrong. Just be sure to use use top shelf digital cable and power cords to bring the best out of both units. I started off using a well reviewed budget cable and then audiotioned a transparent PDL 1, and it took my system to a whole other level.
Good luck!
