At 45rpm I could hear a high pitched hum (I assume 200-240hz) but that was a little past the highest level I listened to, which is pretty loud. Leaving the screws out got rid of that. Also, when I screwed in the grommets my motor had a bit of audible hum at 45rpm (the motor itself) but again, leaving the screws out got rid of that. Not surprising results considering we have the exact same table and nearly the same carts.
The table sounds better if you have the hum/rumble or you don't and the new small diameter round belt is an integral part of that. There is newfound detail in the bass, which is tighter, lower and with more impact than before (which was quite a lot). For now, I am using the standard pulley and belt as the new pulley runs a little too slow and the standard pulley runs a little too fast with the new belt, to my ears at least. It 100% sounds better with the new belt but I can wait until Pro-Ject corrects the 60hz pulley size.
I would honestly equate this kit with a better table and/or a better phono stage. Well worth the fairly cheap price, but if you live in Canada or the US wait until the correctly sized pulley starts to ship.
So you just used the belt ? and left out the pulley grommets and screws ?
