@lanx0003 I have not noticed any sound quality difference between the Alpha USB's coax and AEB, this is simply a matter of conveniently switching between to 2 dacs. To connect 2 devices, one coax and one AEB, to the Alpha USB is a good solution if the DDC is easily accessible and you are willing to reach and toggle that tiny switch on the BACK of the unit. I have used this configuration in the past. But it is a pita since i need a ladder or chair to stand on to reach it. (I know, why not just move it closer but then the cables won't reach and a new can of worms gets opened.)
