i mailed someone who bought the dac. this is his reply
"Hi
I have used it (stand alone; a temporary wire-up in a cardboard box, for goodness sake) connected to a marantz63, creek50 and roksan candy it improves on them all though it was a close thing with the roksan. I am now installing it into the back of a marantz4000 wich has turned it from mediocre to fantastic by its introduction. I have compared the DAC directly with the cambrdge dacmagic 2 and the alchemist, it knocks the spots off both of them.
It is difficult to describe the improvement other than saying it is just nicer to listen to. It gives the music more bite without giving you a headache in turn. Although it is the best DAC I have heard, I am still looking for better but I think the budget is going to get a bit steep. I better not tell the wife!
Regards
