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.

The worst - by far - is idler drive, followed from DD and best is Thread Drive (when done right).
But there is a Fangroup for everything :-)
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.

PRAT counts
Here's an interesting test for those of you who
have belt drives, especially those with rubber belts like the VPI's.

Right, but this is based on VPI's ultra low quality. But you find that very
often with the stuff from other Manufacturers, too. Ever checked a Raven
belt? The word "Precision" you find mainly in their advertising
ads.
Try that with a Basis belt :-)
Or try a Timeline, it is a disaster for the majority of Manufacturers, they
aren't able to offer a proper motor, even when you can buy 3 of them.
Based on that inferior Design solutions I agree that a direct Drive can
give better results. But this is not based on its Design, it is based on the
low quality from the others even when they are very expensive. The
majority of owners believe that the offered product (whatever it is,
Tonearm, Cartridge, Speaker...) is simply perfect form the Design, the
Manufacturers and his cohorts are directly sent from God to bring joy to
everyone and it can be made better, maybe only with more money, but
they don't even think about the correctness of the Design itself. Or what
they really get for the money. Most learn by spending money, but even
that does not educate generally.
I am wondering that every Turntable discussion is based on speed only. Like Dev wrote, it is the beginning and it is important. But is that all?
A little more knowledge should be available I think, we have the year 2013 now and serious High End has 5 digits or more and a lot of owners want to spend that money

Agree with Dover. Listened yesterday to a SP10 Mk3 in a Artisan Fidelity Box ... I can't take that serious. More a toy than a serious High End Table. Piano and Trumpet Tones are changing multiple times, depth and physical presence does not exist.
A close friend who lives in Germany has a Platine Verdier which beats nearly everything which is out there. But it is an original one with the original magnets from Mr. Verdier.
The next models were DIY units with various magnets and variable results. They can't be compared, the name Verdier is also used for inferior copies. Mr. Verdier published from time to time some hints on his website to "His Pirates" knowing very well that they will never get it....always funny to read.
The original Verdier is a work of a Genius who solved a lot of Problems modern units still show.
