@mahler123 I’m curious… how is the RFI affecting your system audibly? Are its effects clear to you?
I use Synergistic Research’s Tranquility Base Carbons with excellent results (in full disclosure I am a dealer for them). They are not inexpensive, but they project an electromagnetic field around components to deflect ambient EMI/RFI and suck out trace EMI/RFI within components. In a highly resolving system, these bases add critical improvements in lowering noise floor, removing high frequency hash, and increasing coherence and spatial presentation.
I currently use six of them in my reference system.
