I use the ones available from Maplins... see here: http://www.maplin.co.uk/clip-on-ferrites-32799 there are different sizes for different diameter cables.I use one at each end of each ethernet and mains cable - and also on any DC cables from DC supplies (e.g. for the router and touch). Accepted practice is to loop the cable at least once around the core for maximum effect but obviously this is only possible with thin cables. For thicker cables, just clip them on, they need to be a tight fit otherwise they wont be effective and will also slide down the cable. As far as measuring their effect - if you had an interference problem you could see it on a scope. Otherwise, just listen. Maplins also sell ferrite rings http://www.maplin.co.uk/ferrite-rings-29788 with these you wind a few turns of cable around the ring. These are very effective for mains cables. You can try both types of ferrite on coax spdif and audio cables too. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
