I wonder if one of these XLR to RCAwould help
You should be able to find less expensive models by other Mfgers if you Google around
I also noticed that your CD player's output voltage on the XLRs is 4 Volts and that your preamps input voltage is only 215 MV ... could it be possible that you are picking up some of the noise floor from the CD player because of it's high output relative to the preamps very low input sensitivity ?????????
