If the goal is to get some listening time in on the Sansui, I can see a couple options. One is the method you describe, although it puts two volume controls in the signal path (always a bit of a pain). Another is to get a speaker switch box with the receiver's output and the amp's output both going into it and out to your main speakers (assuming you're still using the same speakers for both the Sansui and the 950 at this point). A third possibility would be a switch box between the 950 and the amp, so you could switch between preamp output of the 950 and preamp output of the Sansui going into the Cinenova Grande. In all three cases, you should be able to have the DV-563a hooked up with 5.1 analog and optical digital going to the 950 and stereo analog going to the Sansui - I use my player that way, with 5.1 analog to the 950 for DVD-A and SACD, coaxial digital audio for DVD's, and stereo analog for CD, all connected to the 950. Obviously, none of these arrangements are optimal, but they would let you at least play with the Sansui while you wait for the son's wedding (and your two-channel system's speakers to show up).
