If the DMA-chip is so picky about the signals, won't it just make it
even more susceptible to interference? Shielding the DMA-clock could
make a difference in situations where the DMA-chip is "living on the

Or is this total BS?

Btw. I've just shielded the AB-wires and the AB-itself, I'm hoping
this will increase stability in 40MHz. It's been up and running for a
good half hour now...
