I would say a key problem is that you are inputting a highish voltage signal into a highish gain amplifier with a noisy power supply. You are then attenuating the input with RV1 which reduces the signal to noise ratio of the system.

I'm running an external amp with a quality power supply and I get no noise at all. There are slight clicks but they are exactly the same in the CMM2.
