Which Signal Gets The XLR Input?

Hi Folks, I have a 4 input Backert Labs preamp. It has (1) balanced input. There are two contenders: A Hegel CDP4 mk II CD player and a streamer I haven't bought yet. I listen to radio a lot but are the balanced connections wasted on the signal quality? Inquiring minds wish to know. All responses are appreciated.  Regards, Scott
