Direct Drive vs. Idler Drive vs. Belt drive

Axelberger,
you need to have a look at real good belt designs, not a platter transported by just one small motor as the most are. You need to have two big motors to the left and right steered by a control unit where you may change the pitch slightly. If you have the chance listening to one or the other table comprising these features (also tape) you will open up your eyes ☺️

Hi @thuchan ,

Yes, 3 motor belt drive solutions like Audio Note or Clear Audio have to be technically excellent in term of Wow and flutter.
I didn’t listen these turntables at my home. They are out of my budget.
I listened 3 motor Clear Audio in other system. It is really good. But I can’t compare it to my stuff, because the system was different (including the cartridge).

What is really matter for me,
I spent $500 for Lenco + SME 3009 + plinth.
Which belt drive turntable in this price range (including second hand) can compete to Lenco? Nothing came even close!!!
I bought EMT 948 with EMT 929 tonearm for 2500 Euro. Which belt drive turntable in this price range (including second hand) can compete to EMT 948?

Problems with two or three motors are: (1) They have to be perfectly in synch with one another, and (2) you now have two (or three) potential sources of noise that could be transmitted via the belt to the platter.  No free lunch.  I also think that we anal audiophiles worry perhaps too much about issues that are in reality way below background, if the product is well made and engineered.  So 2 or 3 or 4 motors (how about that?) might be fine.

Hi @lewm ,

People think that belt drive is a black magic, technically perfect solution.
You just need a heavy platter on a good bearing and you have very low, inaudible level of Wow and flutter. But it doesn’t work this way. At least, mid-price belt drive turntable have a very perceptible level of Wow and flutter, and it is much worse than rumble that good designed, affordable idler drive like Lenco has.

In a synchronous motor the rotor lags behind the rotating field. This angle changes with changes in load There are subtle differences between motors, even with apparently the exact same build. This results in slight differences in this lag angle for a given load between (identical) motors
In a multi motor design, this means that one motor will be the master and the other(s) will slave this. 
The master providing the bulk of the drive torque. 

Consider the implications of this characteristic when 2 or more motors are used to drive a platter
