Many people have this misguide concept of the direct drive mechanism including some insightful writers in the audio press community. In a review of a belt drive turntable, the usually perceptive Art Dudley couldn't help to give the DD genre a shove in a footnote below:
"Of course, I'm setting aside the even less convenient subject of direct-drive turntables, partly because I haven't the time or space to go into them, and partly out of politeness: Putting the record in direct contact with the phonograph's No.1 source of unwanted vibration, whether of high or low frequency, has never impressed me as a terribly bright thing to do." -Art DudleyWith writing like that, how can the general public be encouraged to even want to give DD a try? A very smart and scientifically minded friend of mine who also happens to be an audiophile and never had any experience with direct drive and was surprised to find out the DD motor spins at 33rpm. For whatever reason, his idea of the DD mechanism is that somehow a fast spinning motor like in a belt drive table--his only exposure--is below the platter in a dd turntable. After I told him the platter/motor spins at such low speed he soon realized the combined resonance is only half hertz to be noisy. It was a "Duh!" moment for him. We need more moments like that; it's only healthy.
