FYI, I just bought on Amazon USA theses flat CAT7 shielded ethernet cables
and they are - at least physically - very similar to the original Meridian SpeakerLink cables. I'll post a photo tonight of the two cables next to each other. The plastic jacket of the CAT7 cable is only a tad bit thicker, otherwise almost as flexible as the Meridian cable. It only feels a bit more sturdy. 10$ for 33 feet / 10 meters.
