Direct Drive vs. Idler Drive vs. Belt drive


I'd like to know your thoughts on the strengths and weaknesses of each drive system. I can see that direct drive is more in vogue over the last few years but is it superior to the other drive systems? I've had first-hand experiences with two out of the three drive systems but looking to learn more.

"The problem with Direct Drives is a big oscillating magnetic device directly under a very sensitive magnetic device."
Magnetic fields are easy to locate and measure. If this was really a problem the British audio press would have been posting about this on the front covers of there magazines. They tried everything to kill off the DD revolution that stormed the world back than.
Nothing could ever be better than the idler and belt drive tables they produced, just like the cars and motorcycles from that era. They did everything they could to protect their industry and lied to all of us.  They wrote so much negative and false BS that for some it became a truth. A lot of those myths are still around today as can be seen from the quote above.
I owned a few British motorcycles and they were built crappy, very crappy. Needed constant servicing. I didn't know that till I picked up a BMW motorcycle. Latter a Japanese motorcycle. They were like an appliance. They always worked and worked well. Very minimal service needed.So the British audio press is responsible for all the miss information that keeps getting regurgitated over and over again.
A lot of the higher end Japanese DD TT from the later 70's onward were truly state of the art back than and even today. It takes a lot of money and engineering skill to better them.
Back than, Japanese audio companies were competing with each other and it was company pride that drove them to produce statement tables that sold at a loss. Yes they cost more to produce than they sold for. They didn't care, the sales of the lower tier tables more than made up for it.
Today most TT are belt drive, companies don't have the dollars it takes to develop state of the art DD motors and controllers. Plus it's easy to just route a plinth out of a sheet good product and slap a nice coat of paint on it. Add a cheap motor, bearing and a rubber band and your most of the way there.
Those cheap belt drive TT are not even in the same ball park much less the same zip code when it comes to keeping speed like a older DD table will. A lot of them even refuse to publish basic specs like wow and flutter.

My Gosh I though that propaganda was invented in Germany
(Goebbells) and Sovjet Union (Molotov?).
But my grandad always blamed British for every bad things. 
He looked than in special way at the listener. I was sceptical
because I was able to read ...That is probably the needed
capability for propaganda. 

edgewear, Your accusation than I am Dutch is curious because
I am an (brave) Serbian. But you are right regarding CD invention.
As you should know I am member of analog religion.
Nandric, the 'accusion' as you like to call it was aimed at Philips for their preposterous CD propoganda. Last time I checked this is a Dutch company......
