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?

Didn't Meridian do this on the Aniversary speakers? Or was that on the ID40 input before integrating it as ID41?

I've had a few gadgets where you see the cable wrapped around a ferrite core so that it passed the US (FCC?) EMI tests. To the point that I bought some myself - identical to the link and also some donut style - can't remember why though.

So plenty of evidence to back this up on older kit. Would like to think that newer kit has this built in by design.

It was the cable for the ID40. The ID41 was designed not to need it (IIRC).

A little update. I ordered some more of these ferrite cores, so I could (finally!) add one to the center speaker. The effect was again clearly audible and similar to the effect on the front speakers. I also put the cores on the leads to the DSP33 speakers I use for surround, although I can not hear any difference directly in Trifield mode. It sounds like the ambient matches the sound of the fronts more closely to create a more consistent sound field. I definitely need to check out some multi-channel recordings, like Pink Floyds Dark Side of the Moon.

Now I only need to add one to my sub. I used a different wire on this speaker, so can't use the 3mm cores. I tried a 6mm core from a friend of mine, but that had a negative effect on the sound. Very weird! Maybe I will just connect a standard interlink as well, so I can use the 3mm cores.

Has somebody else who is (still) playing with legacy DSP speakers already give this a try? I love to hear about your experience.
