Cal Alpha Dac v/s Electrocompaniet ECD-1 Dac

I am happy with the Cal Alpha but compared to what?If the ECD-1 is analog sounding with more detail that could be the way to go.Has anyone heard both? Thanks.
I have to assume that the ECD-1 is at least similar in design and performance to the circuitry that EC uses inside their "one box" CD player. If such is the case, there is little comparison between the Alpha and the EC. Sean
