Mag Lev Audio turntable
 

Hi,

when came across news of this product late last year, it looked very much like a scam. Now I'm not so sure.

This link was published by the makers on May 30 this year.

Only 12W of power consumption and the TT floats & rotates 50mm above the base.


How ?

If you want to know about Mag Lev look up Professor Eric Laithwaite -
he was the guy (Imperial College London?) who more or less invented
it. There should be plenty of links from there.

If they can do it with trains, a turntable shouldn't be that difficult.

He was part of it, but he was also a raving lunatic who thought
flywheels possessed magic powers. He was my prof for a while and we
always left his lectures laughing.

** Answers nothing.

When you take into account the puny power consumption, 50mm of lift that disappears when the power goes off PLUS and that a magnetic phono PU must not be upset by strong or rapidly varying mag fields - it looks an impossible task.

But pictures like the ones I linked don't lie.

One of the things I learnt early on was that pictures nearly always lie :-)

** Nah, no they don't.

Pictures don't lie because they don't speak, but of course they can be faked by people with an interest in so doing.

This page from the "What Hi-Fi" site shows Mag Lev Audio's exhibit at the Munich High End Show a month or so ago.

https://www.whathifi.com/news/munich...17-in-pictures

Scroll down about 1/3 of the way.

If you believe in conspiracy theories and consider the whole audio industry is in on the Mag Lev scam - that pic musty be fake too.

Would this not be a bit of an issue for tracking and subsonic vibrations
etc? I can remember the linear motor powered turntable but they had lots of
trouble with induced pick up from the motor coils.


I think the reason the Streathern failed though was the crackpot colour and
design. it looked like an accident in an art college!

He is no longer with us of course. He lost it a bit with his theories on
precession of gyroscopes making it appear the energy equation was not
losing energy as it moved up a slope.

On a different tack. I'd have liked to have seen a verticle turntable with
the lower half of the record immersed in a fluid with wetting agent. I find
wet playing records can actually sound better and of course no static or
clicks unless its been damaged.

Of course if you could get the temperature low enough you could use a
superconducting magnet and lose no power so no stray fields.

Permanent magnets. It runs. It plays records. I saw one at CES this
year. I think it's more for amazing and amusing your friends than for
being a superior way to play records, though I expect that the isolation
from vibration is excellent. Just the thing for playing your old Bob
Dylan or Aerosmith LPs during an earthquake.

** Mike Rivers is a credible enough guy.

So as expected, is uses powerful ( likely Neodymium ) magnets.

There has to be a second rotating table under the main one, out of sight.

My curiosity is WRT the level of field the cartridge is exposed to, and
what effect that might have.

You could do it with something like the stator coils of a dc motor.
Whatever - I'm guessing that the local magnetic environment is nasty
enough that your choice of pickups is pretty limited.

** Lotsa folk have though of that - hence one hears remarks about using a crystal PU.

Many things are not speced, like W&F, so it is no surprise that the mag field above the platter is not either.
