Jeff,
What you report about the Benchmark DAC1 is very consistent with what I observed and many others have reported. To my ears it happens to work well with my speakers so I am happy with a less "full" sound. I have not heard anything quite as detailed as the DAC1 without sounding harsh and I understand that many people will not like this aspect but it suits me. I admit though that there is not a lot in it between one good DAC and another - at least to my "tin" ears.
