Grace Design m902 vs. Benchmark DAC1?

Has anyone tried these units head-to-head? Both are Stereophile Class A, both are well regarded in the pro audio world. One Stereophile reviewer preferred the Grace, but another uses the Benchmark. The Grace has advantage of remote volume control and an additional analogue in, but it is significantly more expensive. I anticipate getting one of these two products to go into my main system streaming Apple Lossless from an Airport Express via toslink. Thoughts and recommendations appreciated, particularly if anyone is in a position to compare the way they sound.
