I recently added several Schaffner EMC/EMI filters to my Farad Super3 linear power supplies. The results are a Significant improvement in clarity and lower noise floor. The midrange is dramatically clearer. I thought my system sounded pretty detailed and transparent but adding the Schaffner filters have taken it to another level. The improvement quite noticeable.
I had ordered the filters because I had been wondering how good the Farad's were at filtering incoming noise on the AC side as opposed to not generating noise on the DC side.
I think the answer is not so good. I think that is why I am hearing such a significant improvement adding the filter right before the Farad.
I have significant line conditioning in the system already with several dedicated AC lines, DC blocker, isolation transformer, and DigiBUSS. But apparently there is still room for improvement.
The Schaffner filters are pretty easy to implement. One side already has an IEC inlet and the other side has built in wire block. I connected some starquad 16awg with an IEC plug and was good to go.
Schaffner filters runs about $48 each for 10amp versions. https://www.mouser.com/datasheet/2/355/FN2660-3049527.pdf
