All of the two-channel inputs are digitized and sent through to the DSP, even in stereo mode. For one, this allows the crossover to be used in stereo mode. The 950 has an option to bypass the DSP for the two channel inputs but the 1050 does not.
The 5.1 inputs, however, are not fed through the DSP so if you're not using them you could connect your phono preamp to the L&R jacks on the 5.1 inputs.
