why is belt drive better than direct drive?

I think there are two questions here: are you more concerned with convenience and lack of maintenance, or the best sound possible?

Direct drive systems certainly tend to: get up to speed more quickly, have more automated features and don't need new belts, but.........there is a definite advantage to the speed consistency of a belt drive system. As was mentioned earlier, direct drive systems tend to constantly speed up and slow down. While a belt drive will typically measure worse than a direct drive, they typically have a more stable beat. I remember listening to a Linn table for the first time about 17 years ago and being amazed at how much it sounded like real music. It really sounded more like real musicians playing than a direct drive table or a cd player. So while a big deal has been made about motor vibration, I think that is secondary to pitch stability. Certainly, the better isolated a table is, the more detail can be retrieved from the record. IMHO, if you want the sound to be the most real, go with a belt drive and get a wall shelf to place it on. So is the next debate MC vs MM cartridges!!!!!

No one can PLAY records on a belt drive. DJs epitomize this concept...still, some people like fast starting, high torque, speed accuracy (frequency generated quartz lock)and electric braking. Those are the features that allow us to PLAY records. That's why DJs embraced the Technics 1200. It was never designed as a DJ turntable. DJs discovered it, though...

My 1200 is undergoing the modification process-$lowly...these modifications will convert it to a true high end Direct Drive TT system. It will harbor a low output MC yet it will still PLAY records.

Psychicanimal, please explain what you mean by "no one can PLAY records on a belt drive" ??? I'm sure that i'm not the only one that got lost on that one.

I think that Fisher came out with a table that should've been the BEST in theory, but like most of their products back in the 70's and 80's, was WAY under-designed. It used magnetic propulsion instead of any form of direct contact to the platter ( belts, idlers, direct drive, etc... all make contact with the platter one way or the other). Since there was NO contact between the drive source and the platter, it would offer the greatest isolation from motor induced vibration. That is, IF it was properly implemented.

As was typical of most "budget" brands back then, they took what could have been a PHENOMENAL idea and implimented it as if it was going to be sold at K-Mart. Low grade parts, no isolation in the chassis, junky tone-arm, etc... Like most other "junk" made back then, it went the way of the wind and a great idea never received the attention that it should have. Sean

Sean, regarding the magnetic propulsion there is a German TT (Gabriel) that works in a similar way, with no contact between the (very heavy) platter & subplatter. The sound is phenomenal -- as is the price, contrary to the Fisher. As expected, the engineering looks top-notch.
Cheers!

Yeah Psychicanimal, I would love to have kept my Denon DP-80 direct drive motor installed in my Mitchell Cotter B-1 Isolation base; the speed accuracy and looks alone were spectacular. The mass of the setup enabled me to drop the stylus in the groove without the record spinning and turn the gain up to 3 oclock with NO howling. I really loved all that precision,stability and immunity to feedback. Then in 1980, I brought home an Oracle and heard my records for the first time.............Frank
