CD Player output to L/R 5.1 input of Pre-Amp

Does the pre-amp processor converts the analog signal from cd analog out to digital and then reconvert that to analog before sending to the amplifier ?
Is it better to connect the cd out to the 5.1 anlog input of the pre-amp instead of regular analog input, so there will be less processing done by the pre-amp ? Is there any difference or they both are the same ? The whole idea for me to use my cd-players DAC instead of the pre-amp.

Thanks for reply.

I've noticed one thing is that sometimes when playing cd's the overload light is on for few seconds on the processor and that because the internal adc is overloaded, so I'm answering my own question "yes the processor is using adc and dac before sending it to the amp".

But is it still process signals if it is hooked up to the 5.1 input ? When I connect to 5.1 input, I need less volume to listen to music as compared to regular analog input and seems to me soundstage is little bit better.

I need to play with both and decide. I just want to find out if anyone have noticed this or know the difference between the processing of signals.

Thanks Soix for your reply.
I've called Parasound and they have confirmed that 5.1 inputs are direct, no digitization is taking place. All the other inputs are going through some sort of processing.
