What kind of techniques did Technics use to isolate the motor from the platter in the SL-1200? There's no such thing as noiseless and vibrationless motor. With the platter sitting right on top of a noise generator, the result can't be good. This speed indicating neon light makes noise too.When I was a young lad, I asked an hifi salesman who carried high end belt drive turntables a very dumb question. I asked," without the neon light and the dots on your turntables, how can you tell whether if the speed is accurate?" The salesman gave me a simple answer, he said," you listen to it." That's how audio hobbyists were misguided by the Japanese made direct drive turntables.
Listening right now and not a "zzzz", "brrrr", gzgzgz or hum to be heard--just a few ticks of the vinyl. And the wonderful sounds of Gotan Project and Love and Rockets of course.
There isn't going to be any "motoring sound" like from a electric motor of a winch. Micro vibration and noise probably would make the music sounds more like in a tin can. The best way to find out is to compare your "direct drive" to a well made belt drive turntable.
Bite me.
The electric motor in a Technics DD tale rotates at a very slow 33.333333rpm. So, no motor noise of any consequence. The problem that needed to be overcome is a phenomenon called cogging. As the drive is passed from pole to pole in the motor, there is a handoff that can be detected if the motor has too few poles. Technics (and others) overcame that problem by increasing the number of poles to the point where cogging is undetectable with instruments.
My Technics SL-1300 from the 70's, and the Technics S*Q-30* whatever with P-mount arm from the early 80"s sucked. Both were praised by Julian Hirsch, and both are direct drive. I am glad all my turntables now have belts.
Now before direct drives are ruled out altogether remember that the grand daddy of all transcription tables was the EMT 950. This is the Studer PR99 of turntables for professional use. This was a direct drive turntable.
Julian Hirsch? You have to be kidding. J.Gordon Holt feasted on that clown 30 odd years ago when he was bringing Stereophile to life. Citing Hirsch makes you look very out of touch.
But many statement tables have surfaced in the years since which utilize direct drive.
