An acquaintance of mine advised to add ferrite cores to digital interlinks. I know that these are used on some other types of cables, but I have never seen them on digital interlinks. Considering the standard Meridian speaker interlink cables are quite long (8m or 14m), they certainly work as antennas and pick up lots of EM noise, so this could make a difference.
So I ordered some of these 3mm clip-on ferrite cores
and they arrived this weekend. They fit snugly around the cable (I put them only on the SPDIF wire, not the serial comms) and the result is amazing. The clarity has increased and any sharpness has disappeared completely. If I exaggerate a little, it is like a curtain that hung in front of the speakers has been removed. Best investment ever, and the cheapest one. It makes you wonder why Meridian did not fit these by default on the cables?
Just wondering, has anybody done this before and what are your experiences? Any other mods to the cable, maybe shortening it to the needed size?
