AI Modulus 3A vs. Precision Fidelity C7/A Revised

Hi, we have a Precision Fidelity C7/A Revised and are wondering if anyone has compared the C7/A to the Audible Illusions Modulus 3A with the Gold MC Phono Board. I am very hesitant to sell the Precision Fidelity towards investing in the Audible Illusions because the Precision Fidelity does sound quite good and is very difficult to find. Yet, if the AI proves a better unit overall with the Gold MC phono board, I might be willing to part with the PF C7/A. We listen to a low output MC cartridge attached to a Basis Ovation and use a Threshold S/500 amp powering a pair of Innersound Eros.
