Default Degaussing signals

Why do demagnetising sweeps improve sound??

Degaussing signals, CDs and sig gens have been avaialble for sometime and do seem to work from phono cartridges, to replay chains, and even power supplies.

I have used demagnetising CD for sometime but now I have installed Multiwave II+ on my PS300 ac regenerator. This has a @Clean@ function which passes a 60s sweeep at different frequencies thru' the power supply. To my surprise, this makes a BIG difference to:

1. Krell 20i used as a transport and supplied by the PS300 alone. Tames hf spit and improves lf resolution.

2. Krell 20i and dCS972/954 combination fed from the same source and 'demagnetised'. Difference is less than 1 but clear improvement in replay.

Why is this? Degaussing a power supply seems an odd thing to do, unless some change is made to the magnetic field?

By the way, changing the frequency of the power supply from 50 to 120 Hz also makes a great difference. This I can understand to some extent

Though degaussing may or may not have an audible effect in given situations, these gadgets (CDs and the like) perform no degaussing function. Their operation appears to be on the imagination rather than the physical systems. I'm not familiar with the PSAudio gadget, but the ads and reviews don't look promising.

Deguassing CD's improve the sound because they cost money... if they were free; then there would be no noticable effect.

Music CD's contain a broad spectrum of sine waves and will delouse your system as you play...
