Direct Drive turntables


I have been using belt drive tt's. I see some tt's around using direct drive and they are by far not as common as belt drive ones. Can someone enlighten me what are the pros and cons of direct drive vs belt drive on the sound? and why there are so few of direct drive tt's out there?
Thanks

The problems associated with direct-drive were well known to the guys who designed the very best direct-drive turntables of the 1970s and 1980s, which was not exactly the Dark Ages in terms of electronics and engineering. The very best direct-drive tables of those days dealt with the issues in very effective ways. In many cases, their work fell down, if it fell down at all, at the level of plinth design and implementation. Poorly designed plinths account more than anything else for the colorations that one perceives in the mid-level Denon turntables, for one example. With a little ingenuity, one can build much better plinths for these products which mitigates their sonic character. Another source of sonic coloration may be that the built-in motors radiate EMI that can possibly pollute the signal at the cartridge. We now have very effective shielding materials that can eliminate such problems. The DIY effort is well rewarded. The same is true for the best idler drive turntables, despite their dismissal by "Elizabeth". If you want great sound for less money than any comparable belt-drive table, I would encourage you to experiment with top quality direct- or idler-drive turntables of the good old days.
Not all DD are equal. My Lt-30 is magnetically driven and has been superbly upgraded. It is also a linear arm. Generally Elizabeth's opinions have merit, however, not this time.
The disco days most likely help encourage the direct drive turn tables.The DJ's could back cue.You could manually rotate the platter backwards without worrying about damaging the drive system.Doing that on a belt,or idler drive could cause damage to the drive system.That was the major benefit I know of.♫
