I've been thinking about getting a demagnetizer to make my old records
sound better. I've seen them advertised and wondered if they were any
good and what kind of difference I could expect once I've invested in
one.
This is to go with my old Amstrad stack unit which is in my bedroom. Do
you think it would be a worthwhile buy for me?
ahem The above has all the signs of being a wind-up (gramophone?) :-)
However, in the implausible event that the question is genuine, then the
answer is simple.
LPs are made of polymer materials ('Vinyl') with essentially no 'magnetic'
properties. They are played with a cartridge that detects mechanical
movements, not variations in the magnetic state of the LP.
Thus despite the technobabble in the adverts, the only relevant and
observable 'magnetic' effect of the 'record demagnetisers' is to help
salesdroids to drag money from your wallet and into their bank account.
:-)
Thus the main 'difference' will be to your wallet. There is no reason to
assume the LP will sound any different when played, despite the claims.
If the records are clean and in decent condition, then 'better' replay
equipment may make sense. Spend the money on that if you want to improve
the results. Although if you've been playing them on an "Amstrad stack" I
have my doubts they will ever again sound like new. Would probably make
more sense to buy replacement recordings - but don't then play them on the
Amstrad! :-)
Slainte,
