The inputlevel and the impedance isn't the only problem here.

In a phono-input of a receiver there is a so-called RIAA-filter,
which will tear-up your nice CD-music (damping the higher freq.).

My suggestion is to make a switch between your aux-signal and
your CD-signal, as they both have the same level and impedance AND
don't involve nasty filters.
