Are you using balanced cables between them or single-ended? (rca) YBA had a nasty habit in the past of putting "balanced" aes/ebu outputs on their CD players, but they didn't have a truly balanced (differential?) circuit. So, when you try to use balanced cables to a balanced preamp, you got hissy noise...
Either way, you sould try running your CD player into another system and see of you get the noise there too. IF it's quiet, then the problem lies somewhere else...?
