Pros and cons of belt drive Versus direct drive


Would like to hear opinions and facts of belt drive TT versus direct drive TT. Thanks.

Thank you all for your input. I have a Denon DP80 that I am thinking about using in a custom installation. Was curious about thoughts on DD.
Thanks again.
Good explanation, Celtic. It's all about proper design. I was told by Bill Parish (GTT Audio) that his TT for demoing equipment (I don't think he sells TTs) is a rim drive made in Switzerland. Told me it's so precised and rugged that it was used to cut masters. Which brings the point that masters are not cut with belt drives. Anyone who says belt drive is superior is biased.
If you could make a perfect motor direct drive might be better. As is motors are not and the cogging effect took direct drive out of high end. Garrards are still popular in GB but I dont think they can compete with good belt drives. It only makes sense to isolate the motor with a belt.
I agree with Abstract7; direct drive can be as good as belt drive if done right. If I recall correctly, the Goldmund Studio is a direct drive table based on a Technics SP-10.
I think in general belt drive is better. But if done correctly (to isolate vibration) direct drive can be better. Why do you think Rockport Sirus III (at a mere $75k) uses direct drive, and their lesser Sirus II uses belt drive? It's expensive to do direct drive right (although I doubt it's as expensive as the difference in price on the Sirus II vs III).
Dlh,

It's not that simple. There are basically three designs with many variations: direct drive, belt and rim drive. All are actually quite viable if done properly. The argument of motor isolation is correct. I owned a very nice Denon direct drive thinking it almost state-of-the-art until a belt-drive clearly displayed all of the sought after attributes of blackness and superior sonic musicality.

I replaced the dd and lived in bliss. A friend with some very big dog equipment last year purchased an older Luxman dd table, set it up with his older Sumiko 'The Arm' and a new Grado wooden body cartridge. So far this table has embarressed all comers to include Linn and Sota.

Many years ago one of the tables to own was the rim drive Dual 1229 which still sounds quite viable today. To quote, "It's not what you do, but how you do it".
No contest. Belt drive is light years better in terms of sonics; lower noise floor, cleaner signal, etc. Motor isolation is critical because of cartridge sensitivity.

DD turntables were built because they were cheaper to make at a low price point and owners didn't have to mess with belt replacement. Now that there is no mass market demand for turntables, there aren't too many DD models to choose from. Most of us who still have turntables or those who are in the market for turntables are looking for an improvement over digital, hence most, if not all, "audiophile" turntables are belt driven.

Of course, for DJ use DD is the way to go because one could simply hold the platter (or move it back and forth) for easy cueing and sound effects.
