I use them, but I haven't really identified an audible difference. I live in an area where there isn't a lot of steady electromagnetic noise. Perhaps there is an audible improvement when a noise source comes close (e.g., electrically noisy diesel motor).
I understand the principle of better shielding, and I believe it is desireable. I believe my system can sound audibly better based on the cumulative benefit of a number of individually inaudible improvements, and this could be one such.
