While CD-4 recordings were made with 30+ KHz carriers on them, those
signals were cut at very low levels. Playing them tends to erase them
after a few playings, even with the best cartridges and stylii. People I
know who have experimented with CD4 tell me that about 10 playings is it.


Depends on many factors. My B&O MMC6000 could still recover the carrier
after *FAR* more playings than that. Of course the actual surround signal
was pretty crap to begin with on most (all?) CD4 records, just as might be
expected from such a compromised system.
