Albertporter...I won't debate with you whether existing DD turntables exhibit "cogging", but, speaking as one with some experience with (non-audio) DD precision servos, "cogging" would be a flaw in the design. It is no more inherent to a DD system than to an indirect drive such as a belt or idler wheel. A DD system avoids problems of compliance (belt stetch) or backlash in the torque transmission hardware.
Ready to try vinyl
I would like to buy a turntable just to see what all the fuss is about. Since I remember the pops and scratches all too well, I do not want to spend alot just to satisfy my curiosity. I want a turntable that is capable of giving me a "taste" of what the vinyl sound is all about without going overboard. I can always upgrade if I like what I hear. I would also like to avoid deciding against vinyl because the turntable was not capable of capturing at least the basics. What turntables should I be looking at and how much should I spend? I would prefer to buy used due to the experimental nature of this adventure. Current gear is Sunfire processor with phono input, a pair of Classe M 701's, and B&W 800N. I am relying on your responses since I don't know squat. Thanks for your help.
