After market Motor + Belt drive for Verdier


I have been looking to upgrade my TT motor and belt drive for some time now. I use a Nouvelle Verdier and its only sore point is its motor and silk thread drive. It is not bad, it gets the job done. The sound is neat and in general non-offensive. However, when I used a 0.25 inch magnetic tape (reel to reel) to drive the platter the overall sound became more dynamic, voices sounded younger, instruments sounded happier. It was as if the pitch of all the instruments became more realistic. But then I also heard more of the irregularities of the motor rotation, the timing of instruments messed up a little. The background was no more as clean as the thread drive.

This told me two things:
1. Silk thread is good but it affects music in a way that makes the performance a bit sleepy.

2. The stock motor is not good enough to accommodate a tighter coupling with the platter.

So, I am now looking for after market motor and belt drive solution. I looked at Teres motor but for that to work they require a sensor to be placed under the platter but my TT doesnt have enough gap between the platter and plinth to place the sensor. I am looking for some viable suggestions here.

A friend of mine suggested me to consider a flywheel between the motor and the platter which will absorb the motor irregularities. I dont know if it is worth a try because I see many good TTs do not have a flywheel, that means a good motor is all I need I guess but I am open to the flywheel idea also.

Maril55, my fishing line says .28mm diameter (nylon). Here is the one I bought:

Ct0517, I know some people use the monofilament fishing line also and they supposedly great. I wanted to keep it simple so I tried a nylon fishing line of super strong variety and not very thick.

Guys please try this out. It costs nothing but could be an ear opener for sure.
Thank you Pani,
That line is not braided, is it?
How soft is the line, comparing to the silk thread?
Another idea- Walker Audio recommend 2-4 mm silk belt for their Proscenium Black Diamond TT, they supply the belt with the TT
I'll contact Lloyd Walker, who happens to be a member of out local Audiophile club, with some questions

Maril555, yes you are right, it is not braided. It is quite a bit harder than the silk thread but still soft ennough to be used a string. Can you not borrow Mr.Walker's belt to try out ?
