I think the 1200 is a decent sounding DD deck. However, I don't agree that it is better than a decent belt drive. Yes, I am fully aware of the inherent problems in both systems. I have done comparisons, and I always liked the decent belt drive better, although I admit, that it may have something to do with my personal preferences in sound.
Heavy platters would be a good benefit to either of these systems, because of some deficiencies in both drive designs. Most good belt drive tables go to this in order to smooth out the rotational stability. The inertia of the platter does help in this regard - greatly. Unfortunately, most DD tables resort to quartz-locked speed controls and light platters which "hunt" constantly, and create more flutter which is more easily discerned by the ear. The problems in the belt drive tables result in a much lower frequency "wow" which is less discernable and therefore less objectionable to the listener. Yes, I have read the IAR article which devotes about 5 pages to the ills of various belt drive systems. The specs listed for turntables always combine "wow and flutter" together and show some percentage of them combined, such as W&F- 0.8%. However if the flutter component is 0.7% and wow only 0.1%, that table will have more audible performance objections than a table whose main component is low frequency wow, and only 0.1% flutter. So there is more here than meets the eye on a spec sheet. It is not so much that one is more accurate than the other, but in which ways it is inaccurate. The inaccuracies that are less discernable to the ear, will provide better sounding listening because the ear is not noticing them as much as the other type of inaccuracies.
I'm sure that Kevin is very knowledgable, but all AC motors cog, and all quartz locked speed controls hunt, and light platters make it worse. Motor vibrations in DD systems do enter the platter because the platter is part of the motor.
Belt drives have "wind-up and release" with rubber belts. They have issues with interaction of the suspension with the drive system. If they use AC motors, then they also cog. If they have automatic speed controls, then they also hunt. What I have selected is a heavy platter to keep the rotational inertia as stable as possible. I have selected a DC motor with no cogging. I use a belt made from Spectra, which has absolutely no stretch, and is a pain to keep tensioned. My motor speed control is microprocessor controlled, to make speed corrections over several revolutions of the platter, so as not to be as audible as other types(no fast hunting). It is optically coupled with a strobe pattern on the platter so that drift is immediately recognized(<0.1%) and correction applied slowly and gently, at the minimum amounts possible. I have no suspension to interact with the drive system. I place the motor "kitty corner" to the arm pivot to make all motor vibrations that may reach the platter, are in the plane of motion that the cartridge does not sense. In short, I recognize the possible problems and choose systems that deal with those in an effective way.
In the end, it is up to the listener to decide which he likes the best. If that is the criteria, then the listener has made up his mind for his own use, and that is the important thing. I like belt drives. Francisco likes direct drives. Fine. As long as we are both happy with our sound, then it really doesn't matter which type we use. I found long ago that nothing is perfect. Not speakers, not amps, and not turntables. Our choices are largely based upon what problems we can more easily accept in our listening tastes. Different products have different weaknesses. Assembling a system that has fewer of the problems that you, as a listener, are sensitive to, will yield a better sounding system - to you. I think that this is what it really comes down to.
That being said, I think it is great that users can promote their various likes and dislikes about the equipment designs. It is helpful to others who are trying to make buying decisions to hear various points of view. I am probably one of the most vocal and opinionated people on this forum. I certainly think that it is good that we can express our views on these subjects.
I still think belt drives are better. :^) LOL!
