Any demagnetization that I or any of my friends have done have Always,slightly,improved sound.However the improvements(a bit more air and opened up stage)don't last all that long.The process has to be repeated fairly often,and for that reason,I myself only do it on the EVE of a listening session,when my most HYPER-CRITICAL friends come over!THANK GOD that is not too often!!Any other times I have to rely on the fact that I like the sound of my stuff as is!!
