I had the same question that has been posted, few months ago. I read and asked questions and this is what I have done and I love it.
i have a lumin mini u1 streaming via cardas clear aes/ebu interconnect to my qx 5 twenty. I got the basic qx-5 without a internet or streamer. The qx-5 functions as a pure dac, with the volume bypassed. They feed to a kx-r twenty which feeds a pair of mx-r twenties . All connections are balanced and are cardas clear. My ayre c-5 also feeds the qx5 via the other aes/ebu input .
the qx5 functions as a digital hub with the volume bypassed . I am very happy with the sound.
