The Benchmark DAC1 (HDR) is reviewed again in the latest The Absolute Sound. It's also been heavily reviewed in Stereophile as well. However there's one very similar product that doesn't appear to have been covered at all by either publication that, anecdotally, is preferred over the DAC1 by many audiophiles: the Lavry DA11. http://www.lavryengineering.com/productspage_pro_da11.html
I'm sure the DAC1 is an excellent product but given its already extensive coverage you would do your readers a great service by also covering similar competitive products, such as the Lavry DA11.
