Radio Frequency Interference

Hello,

I’m sure this has probably been covered before here, but, I’m relatively new so I will go ahead and ask anyway.

I recently switched out my tube preamp to an Audible Illusions Modulus. I have read good reviews and it posseses somewhat of a cult following. The rest of my components are a Cary 200.2 solid state Power Amp, Kef r700 speakers, a Cambridge Audio Azur that I use as my DAC with a Sonos Connect. I was using a Rogue Audio Cronus Magnum as my preamp with the power tubes removed. (I realize this is less than ideal since I was only using half of the circuit but, this was always meant to be temporary). I got zero radio interference through the Rogue, however, once I hooked up the Audible Illusions Modulus I immediately started picking up radio frequency. I have tried moving it around a bit to see if this eliminated the RFI but have not had any luck with this solution. Hoping there is an easy fix because I really love the sound quality I am getting when music is coming through the speakers and not radio frequencies...
