I had some comparatively modest mods on MF A3.24 to share:

1. Shield the wires connecting digital inputs to PCB board. Kitchen aluminum foil will do. Multiple layers work better than single one. It's funny that peple spend hundreds even thousands on reference digital cable and leave the digital connecting wires unshielded inside the chasis, in which the RFI are usually rampant. Clip an ferrite core on the wires as well.

2. Shield all the transformers and chokes with steel cages, even the little ones on the PCB board.

3. Damp, with Blu-tak, the oscillator, CS8420, the NPC chip (component number escapes me) and the DAC.

4. Put ferrite cores on the wires from AC mains in to the transformer and the bare wires connecting the chokes.

Without any soldering, I got a play back with almost LP quality as a result.
