Interesting!
In my search for a DAC I had narrowed it down to the Exasound E20 and the BMC DAC1 a few weeks ago. In consideration were Matrix X-Sabre, Concero, Invicta, Hex and the ExaSound. Eventually, ended up ordering the BMC, as I needed the preamp section of the BMC and I got it for a decent price. I am averse to paying list price for equipment unless it's in the sub $1000 range. Since I am overseas on a trip, the DAC is packed and ready to be be shipped on my return so impressions will have to wait.
