extrange connection?


I have a problem that I want to share with you to hear your comments:
My CD player have its own analog volume so can be connected to the amp directly thru xlr outputs. My preamp have rca outputs. My idea is to connect both outputs to the xlr inputs of my amp using a special cable that could have in one end a pair of xlrs and in the other end two pairs of cables, one RCA (to my amp) and other xlr (to my cd player). I understand that I cant drive the preamp and the cd at the same time. -Hope you understand my idea-
How sounds this to you; do you think I can loose some quality? any other idea?
Thanks for your imput.

Thanks for your answer but no, my CD player does not have digital imput (by the way, is the new Cary 303/300). About my goal yes, my idea is to run the CD player directly without connections to the preamp and the rest of the sources (mainly dvd-video, dvd-audio and sacd thru the pream).
Sounds like a bad idea to me--if the both are switched on, aren't you going to be running something strange into your amps--a balanced signal from the CD player and an SE signal from the preamp? If one is off and the other on, seems like you might be doing something like adding some weird passive element to the line level signal path, even if it is in parallel--plus I'm not sure how the XLR to SE conversion is done, but I might also worry about shorting something out.

I've tried to run sources w/volume controls direct into amps, and didn't like the result. Before you mess around too much with trying to run it direct, I'd seriously advocate some hard listening with the CD direct and CD through the preamp. It may sound like there is less in the way--and some folks seriously believe in passive attenuators or other ways of going pre-ampless--but I'm not one of them. In my case--driving VT100s from a dCS Purcell, I found the dynamics seriously compromised.
Thanks a lot for your help Edesilva. I'll follow your recomendations before go ahead with my idea.
