No, spontaneous HF loss isn't established beyond doubt by any means, although some video tapes show carrier loss, but that's a different argument. It's just an apparent problem I've had to deal with on occasion when transferring material, either by leaving Dolby off and playing with EQ, or applying HF correction before an external Dolby unit.

I well remember the excitement around cassette becoming a credible hi fi medium - it was indeed a remarkable and swift evolution, almost a revolution.
