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

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.

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?

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.

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.

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.
