George, note that he has three sources, not just a CD player. The model numbers are indicated in his system description.
Zavato, I think I have a fairly nice solution to propose, which I'll probably have time to write up in the morning. First, though, have I correctly determined by researching those model numbers that all three of your sources have both balanced and unbalanced analog outputs? It appears that the Sim Audio 260D with the optional built-in DAC provides both kinds of outputs, as well as the phono stage and the tuner which you indicated do provide them. (I realize that the INT-150 can only accept up to two balanced inputs, and up to four inputs total).
