Magnetization & Demagnetization any conclusions?

I'd be a bit careful about proclaiming the demag of LP's as universally good.I don't know about the Talisman,but though the Furutech did improve some of the LP's we played at a friend(who owns one),it definitely made some discs sound a bit bright to me(only to my own particular tastes).This is a very interesting subject,yet I believe the wealth of acessories available,before we actually spin a disc,is becoming a bit much,BUT I readily admit to being lazy.
A good dry brush,and a decent wet cleaning machine(costing less than my arm or cartridge,hopefully)is all I need! -:)
Best.

The Walker Audio Talisman is in use here. Both on my system and on the systems of some other audio friends, I hear pretty consistent and repeatable improvements when the Talisman is used: greater clarity through the midrange particularly noticeable in the harmonic overtones on strings, blacker backgrounds, often a top end that sounds more extended and pure, better delineation of a broader, deeper and more layered soundstage. The difference is subtle, but very defintely audible and repeatable across four different audio systems.

I agree with Rushton, however, I still don't think its magnetism, but static electricity that we're eliminating.

Has nothing to do with static electricity. You still need a Zerostat for that. Furutech claims in their white paper that there are enough ferrous particles in the pigment used to color the vinyl.

You certainly don't need to spend $1800 or even $200 to get the benefit of demagnetizing. I've heard from some folks who have good success using a bulk tape eraser.

I've been through about 50 different LP's and I've yet to find one that did not sound noticeable better. It is like lifting a veil. It works on CD's as well. I haven't tried it on a DVD but I hear from others that it does improve the picture as well.

I can vouch for the DVD playback. I use my RD-2 for ever DVD that goes into my DVD player. The picture has color becomes much cleaner/less noise if you will.

Bulk erasers was such the item to have during the tape days. Imagine stumbling upon that as time and formats that come and go. Granted, the original use of the device was counter to how it is used in this thread/reference.
