Direct drive vs belt vs rim vs idler arm


Is one TT type inherently better than another? I see the rim drive VPI praised in the forum as well as the old idler arm. I've only experienced a direct drive Denon and a belt driven VPI Classic.

You cannot beat a well designed and implemented idler drive. Maybe some people should listen to an EMT 927 before writing about idler drive. Yes this is the drama with amateurs :-)

What is quite interesting is that there is a clear shift in the direction of higher torque designs. Do bear in mind that Nottingham Analogue go for a high mass low torque design that transmits as little vibration as possible. Likewise the Linn LP12 is not exactly a high torque motor, nor is the one on the townshend rock I recently acquired. That said all three of these decks sound excellent in their own way. A truly circular (hope you don't mind the pun) discussion. As I have said earlier my hearing has changed (or the grass is greener on the other side) and i am beginning to favour the high torque drive and boogie woogie of an idler.
Quite a difference between Nottingham and Linn tt's. The former use massive platters with a low-torque motor. The latter use a light weight platter with a low torque motor. The Nottingham philosophy has merit, IMO. Quite a few very expensive turntables are of the high mass/low torque type, including Walker Proscenium, etc. There are even a few direct-drives that ascribe to the low-torque/high mass approach, e.g., the Kenwood L07D. This can work very well if well engineered. I am not a "Linnie", obviously.
I am always fascinated from technical solutions and an idler drive is THE best (by far) way to transform any vibration and smearing from motor to the bearing and platter. These distortions are called Rhythm (well, the" Subway below Kingsway Hall" in every record), the loss of High frequency information is a result in better Bass (like a compressed MP3 file to the midrange). Most record stations replaced those units as fast as possible. Personally I think, the audiophile world waited for them. Here is a version with an updated motor.
