Hammy, Your quote about motor noise in a dd turntable shows that you do not understand the mechanism. You should read Hiho's post above, as well as a few others that came after yours. A motor consists of a rotor and a stator. In a dd turntable, the platter and the rotor are one and the same thing, so there can be no vibration of the kind you describe. Also, it would not hurt to listen to a properly restored and re-plinthed vintage dd before you make up your mind. If you listen to an old piece of junk that has leaky aged electrolytic caps inside, that's OK with me, but don't judge the whole genre on that basis. At this point in my audio life, and after 35 years of listening mostly to bd turntables, I have fallen irrevocably in love with a few great idler and dd turntables that I restored/replinthed to a high level, and I ain't goin' back.
