If it's a CD player only, it'll only have stereo analog outputs, in which case you would connect it to a stereo analog input and then configure that input to use the analog stereo bypass (which insures that the 1070 doesn't convert from analog to digital and back for DSP). If it's a DVD player and it supports DVD-Audio and/or SACD, you would want to use the multichannel analog output to allow the use of those two formats. For a DVD player without DVD-A and SACD support, I'd treat it just like a CD player for these purposes and use stereo analog output. For either DVD player (with or without DVD-A/SACD), I'd still retain a digital audio connection to use with DVD's.
