Yes, it lifted a fuzzy veil of magnetic pollution that had previously hidden smaller musical detail, caused a degree of listening fatigue, and somewhat diminished the size of the sound stage. This is a definite improvement but cannot be comparared in scale to the larger benefit of reducing exposure of the amplifier circuit board/ other internal components to magnetic interference by shielding the toroidal transformer.

For anybody interested, the LFD RCA input unit (what LFD calls 'Interconnect PCB Board - Phono Block') comes with four magnetic stainless steel screws retaining it to the chassis. So compared nylon to brass as replacement screws and found nylon screws sounded better (less bright).
