I did some very crude testing for RF emissions of the nCore modules and SMPS 600s during playback with them just sitting on an amp stand. This allowed me to get the best ideas for where, and in what direction the airborne noise is worst, and I used this information to inform my layout in the chassis. I found that by having a full size chassis I was able to get enough physical spacing between the modules to not be concerned about interference. Note also that to make an effective shield for RF really requires aluminum at least a 1/2" thick, so distance really becomes the more practical method.
I would not recommend removing the speaker terminals for anyone who is not confident in their ablities, but it is not hard with a good temperature controlled iron, a solder sucker, and some patience. You do have to remove the heatsink to do it properly, and the board is tight there, you really need to be careful not to heat things up too much, as it would be possible to damage the board and adjacent components. I did it because the speaker terminals are brass, and the screws are steel, and I would rather not have those less conductive materials in the signal path.
The blue box is filled with some RF damping compound (secret formula, got to have some mysery right!), and no, I did not A/B the Supreme Fuses vs the OE ones, but they do have substantially less measured R than the stock ones. The Supreme Fuses have proven to be good for me previously, so I just went ahead and added them.
