Any real sonic improvement using 2 or 3 belts on VPI tables?

+1 @tooblue 

I will say that at some point I'm going to order a custom Mark Baker belt for my VPI tt project that uses a ADS/SDS pulley w/ my ADS.

Just for kicks.

I only had 2 belt to work with. I am going to try a third just for the heck of it.

I have a VPI Prime, use an Eagle/Roadrunner, currently use 3 belts with an HRX pulley, which as already explained is a necessity.  I found an incremental improvement with 2 belts, but adding the 3rd belt did not make any noticeable change. 

I have the Eagle/Roadrunner to correct the speed. Once I get the new pulley, I will use the Fieckert software to compare the difference between one,two, and three belts.

My table is a VPI  Prime and just added a Single Motor Flywheel Assembly that comes with the HRX  pully already installed. Might also mention that I have the SDS speed controller which you will need to switch speeds otherwise you are limited to 33.3 rpm.

tooblue,
I saw that pulley and was not sure if it would work on my classic. I'll call Music Direct today and get one. I already have several belts so I don't need them. What table are you using the multiple belts on?

To use more than one belt on your VPI you must upgrade your motor pully to the HRX motor pully, $80.00, once done you can use multiple belts, I use two belts and have tried three belts but could not hear an improvement with the third belt where two belts was quite an improvement over one belt.

stevecham,
The Avenger has a pulley that is not conical. The table is shown with 3 belts.

I use two on my classic and according to my rpm gauge I get slightly better speed control.

VPI pulleys have different levels (speeds) built into the slight conical shape so it makes zero sense to use more than one belt; they will fight one another with increased friction. I have an Aries 2. I would like to try floss though, that sounds interesting.

rim drive......

I did have a scout several years ago and tried the floss. The platter was much lighter. I have not tried it on my Classic. 

I am interested in the 3 belt because I am going to build a table and wonder if 3 belts is worth the effort?

My understanding is that different levels of the Classic pulley have slightly different diameters.  

 I have a TNT three and I found the best improvement by far was to go to dental floss.  I found the belts to degrade the sound so I would have a tough time understanding how more could be better.
