Good anoon everyone,I am currently running an RY-5500/RX-5000 trough aramid thread. Was wondering wht wd be the ideal thread tension for the system. Wd it be better being tight or loose ? Both cases I get constant platter speed, my question is more related to the sonic performance of the system. Wd I be better off using a rubber belt instead ? Wht's yr experiences ?Tks/rgds Ciampa.

Ciampa, in my experience there is absolutely nothing that changes sound on large Micro tables. I did not make those experiments with my RX-5000 but I made them with RX-8000. Whatever I used, from magnetic tape to threads and different types of belts with different tension still gave me the same basic results.

I use light, flat rubber belt without notches. I run it not normally but in the indentation of the platter. I tent to run it relatively loose, the advancing side of the pulley shall not “hang” but to have very-very minute sag. I see no sonic advantages in it but there are some practical advantages: sometimes (more than a few times unfortunatly) I turn air suspension off but forgot to turn the motor off. In this case if the tension too high then I might burn the motor. In my case, since the belt is not too hard on the pulley the pulley can turn and split. Running like this for a day the motor get hot but it did not experience a catastrophic failure.  Do not ask me why I did not synchronize the air pump with motor switch. It is in my list to do for 10 years….
