Got rid of the noise floor with resistors. The KAV-400xi has really high gain so the noise floor is obvious. Used 100ohm and 3ohm 10W Dale Vishay resistors. Would gladly send you the resistors I used for the KAV-400xi for dirt cheap. I use no resistors on my FPB-300cx which has almost no noise floor.
