Have you noticed a difference with high frequency reproduction before and after use? Is there any documented proof of this working?

Here are some topics regarding on how to demag and whether you need to demag or not to demag your tape heads.

I just demagnetized the heads on my Sony TC-850 to hear if there was any difference. It's very subtle, but I've always noticed a small increase in output and a very slight increase at the high end. (The tape plays both louder and brighter.) Nothing dramatic, but noticeable. I've been demagnetizing heads since around 1960 and have always noticed this effect, particularly after I've been playing vintage tapes for a few hours.

Many decks have seen little use and aren't significantly affected. It's most noticeable with record heads vs playback heads, so if you are not going through the entire bias/record/playback cycle, you may not notice it as much with just playback only.

It sends a signal at high DB then automatically lowers it, then repeats it. I hear a marked difference before and after. It is useful to do this, as well as cleaning the heads, before you record.
